Chelate von β-Dicarbonylverbindungen und ihren Derivaten. XVII. Zur Kristallstruktur von Bis-(thioisobutyrylacetonato)-nickel(II)

The x-ray structure analysis of the title Ni^II compound being of the planar coordination type NiS₂O₂] gives Ni? S distances of 2.15 Å and Ni? O distances of 1.87 Å. The sulfur atoms are arranged in cis-position. In the chelate ring the C? C distance is shortened in sulfur neighbourhood. This indicates a fixation of the C?C double bonds in the complex.
