Abstract

CoN5NO(Br)2 crystallizes in the orthorhombic Cmcm space group. The structure is zero-dimensional and consists of eight hydrobromic acid molecules, four nitroxyl molecules, and four CoN5 clusters. In each CoN5 cluster, Co2+ is bonded in a distorted single-bond geometry to five N+1.67- atoms. There is one shorter (1.50 Å) and four longer (1.96 Å) Co–N bond length. There are three inequivalent N+1.67- sites. In the first N+1.67- site, N+1.67- is bonded in a distorted T-shaped geometry to one Co2+ and two equivalent N+1.67- atoms. Both N–N bond lengths are 1.42 Å. In the second N+1.67- site, N+1.67- is bonded in a distorted T-shaped geometry to one Co2+ and two equivalent N+1.67- atoms. In the third N+1.67- site, N+1.67- is bonded in a single-bond geometry to one Co2+ atom.
