Özet

Three new heteronuclear hexacyanometallate(III) coordination polymers (CPs), [Cd3(mu-3ampy)4(H2O)4Cr2(mu-CN)8(CN)4]n (1), [Cd3(mu-3ampy)2(H2O)2Fe2(mu-CN)5(CN)7]n (2) and [Cd3(mu-3ampy)4(H2O)4Co2(mu-CN)8(CN)4]n (3), were synthesized with 3-(aminomethyl)pyridine (3ampy) ligand. All CPs were characterized by FT-IR, Raman, elemental, thermal analysis as well as single crystal X-ray diffraction and powder X-ray diffraction techniques. The single crystal X-ray diffraction analyses shows that the CPs 1 and 3 are two-dimensional structures, whereas CP 2 is a three-dimensional structure where two adjacent metal ions ions are linked via 3ampy and CN bridges. The coordination spheres of all CPs show distorted octahedral geometries. CP 3 was mainly tested as heterogenous catalyst for peroxidative oxidation of benzyl alcohol and its derivatives (4-chloro, 4-bromo, 4-methyl, 4-metoxy and 4-nitro benzyl alcohol). From the results, the highest aldehyde formation was obtained from the oxidation of benzyl alcohol with overall yield as 100%. In addition, catalytic reactions exhibited high selectivity towards aldehyde and no over-oxidation product (carboxylic acid) was observed.
