Abstract
The crystal and molecular structure of [Co(NO)(ketox)2], where ketoxH is 2-hydroxyacetophenoneoxime, have been determined. This nitrosyl crystallizes in the orthorhombic system,a=14.741,b=6.853,c=32.442 A,Z=8, space groupPbca. The structure was determined by the heavy-atom method, using Mokα diffractometer data, and refined by full-matrix least squares toR=0.041 for 1768 observed reflections. The molecule excluding the nitrosyl group is approximately planar. The cobalt atom is 5-coordinate in an essentially square pyramidal arrangment with the basal plane defined bytrans bidentate oximato ligands between which are strong hydrogen bonds. The nitrosyl group occupies the apical position and the Co-N-O angle is 126.3°.
