Özet
Two new heteronuclear Cd(II)/Co(III) compounds, {[Cd(1-meim)3Cd0.5(1-meim)Co(mu-CN)4(CN)2]}n 3 Cd 0 . 5 (1-meim)Co(mu-CN) 4 (CN) 2 ]} n (1) 1 ) and {[Cd(1-etim)3Cd0.5(1-etim)2Co(mu-CN)3(CN)3]& sdot;H2O}n 3 Cd 0 . 5 (1-etim) 2 Co(mu-CN) 3 (CN) 3 ] & sdot; H 2 O} n (2) 2 ) (1-meim: 1-methylimidazole, 1-etim = 1-ethylimidazole), have been synthesized and characterized using elemental analysis, FT-IR and Raman spectroscopy, single-crystal X-ray diffraction techniques. The single crystal X-ray study shows that the compound 1 exhibited a 1D double chain structure and is further linked into 3D supramolecular architectures through C-H & sdot;& sdot;& sdot;N - H & sdot;& sdot;& sdot; N and it & sdot;& sdot;& sdot;it & sdot;& sdot;& sdot; it interactions. Whereas the compound 2 displayed 2D network which is extended into a 3D supramolecular framework by O-H & sdot;& sdot;& sdot;N - H & sdot;& sdot;& sdot; N hydrogen bonds and C-H center dot center dot center dot it - H center dot center dot center dot it interactions. In 1 and 2 , each Co(III) ion is coordinated by six carbon atoms from cyanide ligands, thus showing an octahedral coordination geometry. Cd1 and Cd2 ions exhibited two different geometries, distorted trigonal bipyramidal and octahedral. Furthermore, phase purities, catalytic and thermal properties were investigated.
