“…lately, due to applications. [1][2][3][4][5][6][7][8] The dual-core metal center complexes, which could activate some of the methane monooxygenase enzymes, aminopeptidase, urease, as well as various life phosphoesterases systems play an important role. [9][10][11][12] Therefore, the understanding of their structural, magnetic, and spectroscopic properties is very important to rationalize their effects on the catalytic properties of the enzymes as well as for the design of new biomimetic compounds.…”

16 , has been synthesized and explained as structure using some elemental analyses. FT-IR spectra, UV-Vis reflectance, magnetic measurements, thermal analysis and x-ray diffraction methods. The results showed that the unit cell of complex includes two molecules Ni II cation, four molecules salicylates as bridge and two molecules N,N-diethylnicotinamide ligands, also there is one molecule hydrated aqua. The compound crystallizes in the monoclinic space group P2 1 /c with the following unit-cell parameters: a = 13.6776(6) Å, b = 10.5238(3) Å, c = 21.8165(9), a = 90.00º, b = 126.546(3)º, g = 90.00º and Z = 2. The compound [Ni 2 (m-Sal) 4 (Dena) 2 ]H 2 O is a typical paddle-wheel complex structure. Two Ni II ions are bridged by four salicylate ligands (O2, O2 i , O3, O3 i , O5, O5 i , O6 and O6 i ) using a m-COOcoordination mode [symmetry code: (i) 1-x, 1-y, 1-z]. Each Ni II also coordinates to one nitrogen atom (N1 and N1 i ) from one N,N-diethylnicotinamide ligand molecule in the axial position. The complex has strong paramagnetic properties.

New series of organotin(IV) complexes and Schiff bases derived from amino acids have been designed and synthesized from condensation of 1H-indole-2,3-dione, 5-chloro-1H-indole-2,3-dione, and α-amino acids (phenylalanine, isoleucine, and glycine). All compounds are characterized by elemental analyses, molar conductance measurements, and molecular weight determinations. Bonding of these complexes is discussed in terms of their UV-visible, infrared, and nuclear magnetic resonance (1H, 13C, and 119Sn NMR) spectral studies. The results suggest that Schiff bases behave as monobasic bidentate ligands and coordinate with dibutyltin(IV) in octahedral geometry according to the general formula [Bu2Sn(L)2]. Elemental analyses and NMR spectral data of the ligands with their dibutyltin(IV) complexes agree with their proposed distorted octahedral structures. Few representative compounds are tested for their in vitro antibacterial activity against Gram-positive (B. cereus, Staphylococcus spp.) and Gram-negative (E. coli, Klebsiella spp.) bacteria. The results show that the dibutyltin complexes are more reactive with respect to their corresponding Schiff base ligands.
