Tris(8-quinolinolato-²N,O)chromium(III) ethanol solvate

D.-X. Li, D.-J. Xu and Y.-Z. Xu

Abstract: The title chromium(III) complex, [Cr(C₉H₆NO)₃]·C₂H₆O, is isomorphous with the manganese(III) compound [Xiong et al. (1995). Acta Cryst. C51, 1978-1980]. Three 8-quinolinolate ligands chelate the Cr^III atom to form an approximately octahedral coordination geometry. An ethanol solvent molecule hydrogen bonds to the complex with an OO distance of 2.758  (5)  Å and an O-HO angle of 167°. The separation distances of 3.426  (19) and 3.368  (4)  Å between parallel quinoline rings suggests the existence of - stacking between neighboring complex molecules.
