“…Furthermore, the band at 1127 cm −1 is attributable to the ν C=N of bipyridine ring, which reveals the complexation of the N atoms from the bipyridine ring of the ligand. [16] The analysis of IR spectrum of the complex is in agreement with crystal structure and charge balance consideration.…”

The title compound, [Ni(dcbp)(H 2 O) 2 ](H 2 dcbp=2,2 -bipyridine-4,4 -dicarboxy acid), was synthesized under hydrothermal conditions. The structure was determined by single-crystal X-ray diffraction and further characterized by elemental analysis, IR, and TGA. The compound crystallized in an orthorhombic system, P2 1 2 1 2 1 space group, a = 6.7665(7)Å, b = 12.9047(14)Å, c = 13.1848(15)Å, β = 90 • . In the compound, each Ni(II) atom exhibits a six-coordinated distorted octahedral geometry. Interestingly, carboxylate group from dcbp ligands bridges between adjacent Ni(II) atoms giving rise to unprecedented interweaving of hetero-chiral single helical chains into a 3D chiral (10, 3) framework.

A novel 3D coordination polymer [Mn(tzda)(4,4 0 -bipy)(H 2 O)] n (1) of mixed ligands, (1,3,4-thiadiazole-2,5-diyldithio)diacetic acid (H 2 tzda) and 4,4 0 -bipyridine, has been hydrothermally synthesized and characterized by single-crystal X-ray diffraction and IR spectra. Complex 1 crystallizes in the orthorhombic space group Pbca with a 5 18.1657(9)Å , b 5 9.0882(5)Å , c 5 22.9333(12)Å . In the structure, each Mn(II) ion is in a distorted octahedral coordination geometry, three among four coordination sites of the equatorial plane are occupied by the carboxylate oxygen atoms and the remaining site is occupied by the water molecule while the apical positions are occupied by two nitrogen atoms from two bipy molecules. The six-coordinated Mn ions are interlinked by flexible tzda ligands to form layers, which are sustained by rigid 4,4 0 -bipy ligands into a 3D open framework. The magnetic property of 1 was also investigated and the magnetic susceptibility data were rationally fitted with J 5 20.103 cm 21 , g 5 2.09, zJ 0 5 20.02 cm 21 , showing weakly antiferromagnetic interactions among Mn(II) ions in 1.

“…Clearly, this particular behavior is due to the presence of the 5-methyl substituent with no electron delocalization. In some 1,3,4-thiadiazole sulfonamides with substituted amino groups, the N1 is the best donor atom because there is a significant interaction between the 1,3,4-thiadiazole ring and the substituted amino group; the negative differential charge on N amino is able to move through the N amino -C1-N1 bonds and stabilize the decrease of negative charge in N1 generated upon coordination [22].…”

“…The versatility exhibited by these thioethers as ligands in metal complexes has not received enough attention. Information on the structural and spectroscopic behavior is very scarce and as far as we know, restricted to the crystal structure of 2-amino-5-benzylmercapto-1,3,4-thiadiazole (C 9 H 9 N 3 S 2 ) [21] and our previous work dealing with some of its complexes [22]. After investigating the coordination behavior of C 9 H 9 N 3 S 2 , particularly towards Cu(II), we wonder how the substitution of resonance donor amino group by an inductive donor group such as methyl affect versatility, crystal packing and H-bond strength in the lattice and ligand coordination sites for 1,3,4-thiadiazole derivative thioethers.…”
