Redetermination of tris(ethyl carbazate-²N,O)cobalt(II) dinitrate

K. Srinivasan, S. Govindarajan and W. T. A. Harrison

Abstract: The present study of the title compound, [Co(C₃H₈N₂O₂)₃](NO₃)₂, probably represents a correction to that reported by Zhang, Song, Zhang, Ma & Yu [Z. Naturforsch. Teil B (2005), 60, 505-510] with a doubled a axis. As modelled here, there are four independent cations, each built up around a fac-CoN₃O₃ octahedron, and eight anions in the asymmetric unit. Two of the cations show disorder in one of their ethyl side chains in ratios of 0.712 (10):0.288 (10) and 0.612 (7):0.388 (8). Numerous cation-to-anion N-HO hydrogen bonds, many of which are bifurcated, help to establish the crystal packing.
