Özet

In this study, four new heteronuclear hexacyanoferrate(III) and hexacyanocobaltate(III) complexes, namely, [Cu2(4mpy)2Cu(4mpy)2(EtOH)2Co2(mu-CN)8(CN)4]n (1), [Zn2(4mpy)2Zn(4mpy)2Co2(mu-CN)10(CN)2]n (2), [Cd2(H2O)8Cd(4mpy)2Co2(mu-CN)8(CN)4]n (3) and [Cd3(4mpy)12Fe2(mu-CN)6(CN)6]n (4), were synthesized using 4-methylpyridine (4mpy) ligand. All complexes were investigated using single-crystal X-ray diffraction (SC-XRD), vibration (FT-IR and Raman) spectra and elemental and thermal analysis techniques. In addition, powder X-ray diffraction (PXRD) patterns were performed to verify the phase purity of the complexes. Crystallographic analyses reveal that complexes 1, 2 and 4 exhibit 2D structure while complex 3 exhibits 1D structure. Also, the 3D supramolecular structures of the complexes 1-4 formed through intermolecular C-H center dot center dot center dot N, O-H center dot center dot center dot N or O-H center dot center dot center dot O hydrogen bonding.
