(Acetylacetonato)aqua(2,2',2''-terpyridine)chromium(III) bis(perchlorate) dihydrate hexamethylphosphoramide solvate

N. Cloete and H. G. Visser

Abstract: The title compound, [Cr(C₅H₈O₂)(C₁₅H₁₁N₃)(H₂O)](ClO₄)₂·2H₂O·C₆H₁₈N₃OP, adopts a distorted octahedral configuration about the Cr^III atom, mainly due to the rigidity of the terpyridyl ligand. The N-Cr-N bite angles are significantly distorted from 90° at 78.3 (1) and 78.6 (1)°. The Cr-N bond distances vary between 1.998 (1) and 2.068 (1) Å. The crystal packing is controlled by hydrogen bonding and -stacking, with an interplanar separation of 3.263 (2) Å.
