The crystal structure of the α form of anhydrous copper 8-hydroxyquinolinate

Abstract

The crystal structure of the e form of anhydrous copper 8-hydroxyquinolinate, Cu(C9H6NO)2, has been determined by the Weissenberg equi-inclination X-ray method. The crystals, of bronze colored, fibrous morphology, were found to be monoclinic in the space group P21/c. The unit cell of dimensions a = 7"40 + 0.03, b = 3"84 + 0.02, c = 24"37 + 0"09/~, and 8= 98 6' +_ 10', contains two molecules. Intensities were measured visually, and the data refined by difference synthesis and least squares with a final R index of 12.2 ~o including all observed reflections. Absorption corrections were neglected.
