The crystal structure of {[Cd(sulfadiazine)2]n[Cd(sulfadiazine)2·H2O]n} (1) comprises of two different Cd centers in which sulfadiazine is used as a quadridentate and bidentate ligand to coordinate to Cd1 center, while it acts as a tridentate and bidentate ligand to bridge to Cd2 center, and the oxygen atom from water also coordinates to Cd2 center. As a result, the title compound bears two different 1D chain. CCDC: 274945.
Compound Zn(phen)3BDA (1) (BDA=6,6′-dibromo-2,2′-dimethoxy-1,1′-binaphthylene-4,4′-disul- fonate, phen= 1,10-phenanthroline) composes of the anion part (racemic-(R,S)-6,6′-dibromo-2,2′-dimethoxy-1,1′- binaphthylene-4,4′-disulfonate ) and the cation part which consists of a racemic octahedrally coordinated zinc center defined six nitrogen atoms from three phen rings to form an inorganic chirality that can be resolution by chiral organic ligand, the 3D framework was formed through the strong H-bonding interaction between sulfonate and water. CCDC: 277924.
The geometry around Co center in bis(4-hydroxy-3-quinolinecarboxylate) bipyridine cobalt(II) (1) , prepared by the hydrothermal treatment of ethyl 4-hydroxy-3-quinolinecarboxylate and CoCl2 in the presence of pyridine, displays a slightly distorted octahedron in which two apical positions are occupied by py and equatorial plane is composed of four O atoms from two hydroxy and carboxylate groups. CCDC: 285591.
