Özet
Three new hexacyanocobaltate(III) complexes, {[M 2 (hmpy) 4 Co( mu- CN) 4 (CN) 2 ] center dot 2H 2 O} n (M = Cu(II) ( 1 ), Zn(II) ( 2 ) and Cd(II) ( 3 )) were synthesized with 2-hydroxymethylpyridine (hmpy) ligand, and characterized by vibration (FT - IR and Raman) spectral, single crystal X-ray diffraction (SC-XRD) and powder X-ray diffraction (PXRD), thermal and elemental analyses techniques. The crystallographic analyses revealed that cyanide complexes 1 - 3 are infinite one-dimensional coordination polymers. Each M ion is coordinated by two nitrogen and two oxygen atoms from the hmpy ligands and two nitrogen atoms from the cyanide ligands, displaying a distorted octahedral coordination geometry. Similarly, each Co(III) ion is coordinated by six carbon atoms from cyanide ligands to form a distorted octahedral coordination geometry. These complexes form 3D supramolecular networks through O - H & sdot;& sdot;& sdot; O hydrogen bonds and C - H & sdot;& sdot;& sdot; N interactions. Additionally, structural analyses such as metal salts, pH values of the compounds obtained under different conditions were evaluated. A synthesis -structural analyses relation was made from these data.
