Reaction of CdII and ZnII thiocyanate with 3-acetylpyridine leads to the formation of the new CdII and Zn II coordination compounds [Cd(NCS)2(3-acetylpyridine) 4] (1A), [Cd(NCS)2(3-acetylpyridine)2] n (1B), [Cd(NCS)2(3-acetylpyridine)]n (1C) and [Zn(NCS)2(3-acetylpyridine)2] (2A). Compound 1A consists of discrete complexes, in which the metal centers are octahedrally coordinated by four terminal bonded N-donor co-ligands and two terminal N-bonded thiocyanato anions. In compound 2A the metal centers are only tetrahedrally coordinated by two terminal bonded N-donor co-ligands and two terminal N-bonded thiocyanato anions. In compound 1B the CdII cations are octahedrally coordinated by two terminal bonded N-donor co-ligands and four thiocyanato anions. The metal centers are linked by μ-1, 3 bridging thiocyanato anions into chains. In compound 1C the metal cations are octahedrally coordinated by two μ-1, 5 bridging 3-acetyl-pyridine ligands and four μ-1, 3 bridging thiocyanato anions building up a three-dimensional coordination network. Investigations on the thermal degradation behavior of all compounds using simultaneous differential thermoanalysis and thermogravimetry as well as X-ray powder diffraction and IR spectroscopy prove that on heating compound 2A decompose without the formation of 3-acetylpyridine-deficient intermediates. In contrast, for compound 1A a stepwise decomposition is observed, leading to the formation of the 3-acetylpyridine-deficient compound [Cd(NCS)2(3- acetylpyridine)2]n (1B) which decomposes on further heating Copyright
