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

Abstract

The title compound, [Cr(C5H8O2)(C15H11N3)(H2O)](ClO4)2·2H2O·C6H18N3OP, adopts a distorted octahedral configuration about the CrIII 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 π‐stacking, with an interplanar separation of 3.263 (2) Å.
