Hydrazides of carboxylic acids are bioactive, and some of them are applied in pharmacology. However, the presence of three functional groups (C=O, -NH-, and -NH 2 ), which are able to interact with each other and to act as donating groups in complexation with d metals, makes hydrazides of carboxylic acids and their coordination compounds interesting for structural studies. X ray diffraction data for a number of hydrazide coordination compounds with metals, including some benzhydrazide complexes, are found in [1]. Literature data on the structures of benzhydrazide coordination compounds with 3d metals concern only complexes with inorganic anions. Information on similar complexes with carboxylates is unavailable.In this work, the coordination compound [CoL 3 ](OH)Cl(Н 3 Ssal) ⋅ H 2 O (I), where L is benzhy drazide (hydrazide of benzoic acid), and Н 3 Ssal is 5 sulfosalycilic acid, has been synthesized and studied by IR spectroscopy and X ray diffraction. EXPERIMENTALSynthesis of complex I. CoCl 2 ⋅ 6H 2 O (2.38 g, 0.01 mol) was dissolved in water (5 mL), thereupon NaOH (0.4 g, 0.01 mol) was added. The settled precipitate was fil tered out, carefully washed with water, and added in portions to a solution of sulfosalycilic acid (2.18 g, 0.01 mol) in water (5 mL). To the resulting solutions, ben zhydrazide (4.08 g, 0.03 mol) dissolved in water (30 mL) was added in portions under stirring. After the precipitate settled, it was washed with water several times and dried in a desiccator over CaCl 2 to a constant weight.Crystals suitable for X ray diffraction analysis were obtained by recrystallizing the powder product from water.IR absorption spectra were recorded as KBr pellets on a Frontier Perkin Elmer FTIR spectrometer (4000-350 cm -1 ).

Prismatic crystals of complex I (С 28 Н 28 ClCoN 6 O 11 S) are orange and tri clinic: а = 9.948(2) Å, b = 13.288(3) Å, c = 14.710(3) Å, α = 109.39(3)°, β = 95.60(3)°, γ = 110.38°, V = 1668.7(6) Å 3 , FW = 751.0, F(000) = 772, ρ calcd = 1.495 g/cm 3 , μ = 5.936 g/cm 3 , Z = 2, space group РThe intensities of 5744 independent non zero reflections (2803 reflections were refined) were mea sured on an Enraf Nonius CAD 4 diffractometer (CuK α radiation, graphite monochromator, θ/2θ scan ning, θ max = 70°).The structure was solved and refined by least squares (on F 2 ) using the SHELXL 97 software [2]. Hydrogen atoms were located in calculated positions and refined isotropically with the parameter U H , which was 1.2 times higher than the thermal parameter of a corresponding non hydrogen atom.

“…To determine the kinetic parameters and the rate-controlling step of cerussite dissolution in SSA solutions, the experimental data obtained in the leaching step were analyzed based on the shrinking core model using the rate expression given in eqn (7) to ( 9) and the mixed kinetic models given in the literature. Among the mixed kinetic models applied to the leaching data, the following model could be more suitable for demonstrating the kinetics of this leaching system.…”

In this paper, an attractive organic complexation reaction reagent with lead ions was developed for lead extraction from cerussite. The leaching kinetics of cerussite was investigated using 5-sulfosalicylic acid solution as a lixiviant. The effects of several experimental parameters on the leaching of cerussite were investigated, and a kinetic model was developed to represent the relationship. The leaching process was controlled by a mixed kinetic model. The results showed that the leaching rate of cerussite increased with an increase in the stirring speed, temperature, and concentration, as well as a decrease in the particle size. The activation energy was found to be 37.07 kJ mol À1 . The rate of reaction based on the mixed kinetic modelcontrolled process could be expressed as [1 À (1 À x) 1/3 ] 2 = [k 0 (SS) 6.852 (r 0 ) À1.943 (C) 2.042 exp(À37.07/RT)]t. X-ray diffraction and scanning electron microscopy/energy-dispersive X-ray spectroscopy analyses indicated that a new solid reaction product may be formed.

“…Chemists have already paid a lot of attention to the construction of supramolecular coordination compounds based on the multifunctional ligand 5-sulfosalicylic acid (H 3 SSA) due to its structural and biological interest, which may be attributed to the rich functional groups of H 3 SSA (Fan & Zhu, 2007;Marzotto et al, 2001). To the best of our knowledge, there are still no coordination compounds reported with the multifunctional amino-substituted sulfobenzoate ligand 2-amino-5-sulfobenzoic acid (H 2 asba).…”

Much attention has been paid by chemists to the construction of supramolecular coordination compounds based on the multifunctional ligand 5-sulfosalicylic acid (HSSA) due to the structural and biological interest of these compounds. However, no coordination compounds have been reported for the multifunctional amino-substituted sulfobenzoate ligand 2-amino-5-sulfobenzoic acid (Hasba). We expected that Hasba could be a suitable building block for the assembly of supramolecular networks due to its interesting structural characteristics. The reaction of cadmium(II) nitrate with Hasba in the presence of the auxiliary flexible dipyridylamide ligand N,N'-bis[(pyridin-4-yl)methyl]oxamide (4bpme) under ambient conditions formed a new mixed-ligand coordination compound, namely bis(3-amino-4-carboxybenzenesulfonato-κO)diaquabis{N,N'-bis[(pyridin-4-yl)methyl]oxamide-κN}cadmium(II)-N,N'-bis[(pyridin-4-yl)methyl]oxamide-water (1/1/4), [Cd(CHNOS)(CHNO)(HO)]·CHNO·4HO, (1), which was characterized by single-crystal and powder X-ray diffraction analysis (PXRD), FT-IR spectroscopy, thermogravimetric analysis (TG), and UV-Vis and photoluminescence spectroscopic analyses in the solid state. The central Cd atom in (1) occupies a special position on a centre of inversion and exhibits a slightly distorted octahedral geometry, being coordinated by two N atoms from two monodentate 4bpme ligands, four O atoms from two monodentate 4-amino-3-carboxybenzenesulfonate (Hasba) ligands and two coordinated water molecules. Interestingly, complex (1) further extends into a threefold polycatenated 0D→2D (0D is zero-dimensional and 2D is two-dimensional) interpenetrated supramolecular two-dimensional (4,4) layer through intermolecular hydrogen bonding. The interlayer hydrogen bonding further links adjacent threefold polycatenated two-dimensional layers into a three-dimensional network. The optical properties of complex (1) indicate that it may be used as a potential indirect band gap semiconductor material. Complex (1) exhibits an irreversible dehydration-rehydration behaviour. The fluorescence properties have also been investigated in the solid state at room temperature.
