“…Another aspect of investigating iron citrate structures is that until now virtually only anionic iron(III)citrate complexes with different counterions such as guanidinium, quinolinium, ammonium etc. have been synthesized (Bobtelsky & Jordan, 1947;Liu et al, 2008;Bino et al, 1998;Hao et al, 2001;Matzapetakis & Raptopoulou, 1998;Shweky et al, 1994;Gautier-Luneau et al, 2005). There have also been two iron(II) citrates reported so far.…”

The new compound [Fe(H2cit)(H2O)]n (NICS-2) is the first neutral ferrous citrate carboxylate that has been synthesized up to now. The iron citrate coordination polymer was hydrothermally synthesized and the structure was solved using single-crystal X-ray diffraction. It crystallizes in an orthorhombic space group P2(1)2(1)2(1) (No. 19), with a = 5.9470 (4), b = 10.402(1) (5), c = 13.5773 (7) Å, V = 839.91 (8) Å(3), Z = 4. Its structure consists of one-dimensional chains of corner-sharing Fe(II)O6 octahedra that are additionally cross-linked with citrate ligands. Chains are additionally stabilized into a pseudo-three-dimensional structure by hydrogen bonds. The measurement of magnetic properties revealed that the magnetic moment is almost constant above 100 K (μeff = 5.1 µB), but decreases rapidly below this temperature most probably due to the appearance of weak antiferromagnetic interactions between Fe atoms. Additionally, analysis of Mossbauer spectra confirmed the presence of divalent Fe atoms in the structure. Thermogravimetrical and X-ray high-temperature diffraction analyses showed the thermal stability of the material up to 548 K.

“…In this regard, intermolecular forces, such as hydrogen bonding, halogen bond, pÁÁÁp stacking, CHÁÁÁp/CH 2 ÁÁÁp/CH 3 ÁÁÁp interactions, CHÁÁÁO/CH 2 ÁÁÁO/CH 3 ÁÁÁO interactions, and ion pairing interactions are well-known for making aggregates of molecules and linking discrete molecular building blocks or lowdimensional structures into high-dimensional supramolecular frameworks [8][9][10][11][12][13][14]. Hydrogen bonding is one of the most important noncovalent interactions that can determine and control the assembly of molecules and ions [15][16][17][18].…”

The preparation, X-ray crystal structure, fourier transform infrared (FTIR) spectroscopy, and elemental analysis of three compounds based on diethylenetriamine and aromatic carboxylic acids are reported. XRD and FTIR analysis indicated that all these complexes are organic salt. The compound 1 crystallizes in the triclinic, space group P-1, with a = 8.5665 (8) Å , b = 11.8387(9) Å , c = 12.4901(11) Å , a = 77.2580(10)°, b = 77.1820(10)°, c = 78.290(2)°, V = 1,188.81(18) Å 3 , Z = 2. The compound 2 crystallizes in the triclinic, space group P-1, with a = 8.0040(7) Å , b = 9.4869(8) Å , c = 20.3491(18) Å , a = 84.6370(10)°, b = 87.032(2)°, c = 78.9620(10)°, V = 1,509.0(2) Å 3 , Z = 2. The compound 3 crystallizes in the orthorhombic, space group Pbca, with a = 12.1232(11) Å , b = 13.5714(14) Å , c = 26.179(3) Å , a = 90°, b = 90°, c = 90°, V = 4,307.3(7) Å 3 , Z = 8. The supramolecular architectures of 1-3 involve extensive hydrogen bonding including N-HÁÁÁO, N-HÁÁÁN, and O-HÁÁÁO interactions as well as other non-covalent CH-O, CH 2 -O, O-p, NH 3? -p, CH 2 -p, and pÁÁÁp interactions, giving 3D framework structures.

Two crystalline organic acid-base adducts [(L)Á (Chda), L = 2-aminopyrimidine, Chda = 1,4-cyclohexanedi carboxylic acid] (1), and (2-aminopyrimidine):(butane-1,2,3,4-tetracarboxylic acid):2H 2 O [(HL 1 ) 2 Á(Bta 2-)Á2H 2 O, Bta 2-= dihydrogen butane-1,2,3,4-tetracarboxylate] derived from 2-aminopyrimidine and carboxylic acids (1,4-cyclohexanedicarboxylic acid, and butane-1,2,3,4-tetracarboxylic acid) were prepared and characterized by X-ray diffraction analysis, IR, mp, and elemental analysis. Compound 1 crystallizes in the monoclinic, space group P2(1), with a = 5.2153 (5) Å , b = 18.2803(17) Å , c = 7.3409(6) Å , b = 107.9960(10)°, V = 665.62(10) Å 3 , Z = 2. Compound 2 crystallizes in the triclinic, space group P1, with a = 5.2455(7) Å , b = 8.4637(11) Å , c = 12.0299(15) Å , a = 97.9620(10), b = 98.954(2)°, c = 95.1990(10), V = 519.04(12) Å 3 , Z = 1. Both supramolecular architectures of the compounds 1-2 involve O-HÁÁÁN/N-HÁÁÁO hydrogen bonds as well as CH-O interactions. The role of these noncovalent interactions in the crystal packing is ascertained. These weak interactions combined, both compounds displayed 3D framework structure.
