Materials Data on CoBr2(N3O)2 by Materials Project

CoN5Br2NO2 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of four nitrous acid molecules and two CoN5Br2 ribbons oriented in the (0, 0, 1) direction. In each CoN5Br2 ribbon, Co4+ is bonded in a trigonal bipyramidal geometry to five N+1.67- atoms. There are a spread of Co–N bond distances ranging from 1.56–1.98 Å. There are three inequivalent N+1.67- sites. In the first N+1.67- site, N+1.67- is bonded in a single-bond geometry to one Co4+ atom. In the second N+1.67- site, N+1.67- is bonded in a 1-coordinate geometry to one Co4+ and one Br5+ atom. The N–Br bond length is 1.83 Å. In the third N+1.67- site, N+1.67- is bonded in a 1-coordinate geometry to one Co4+ and one Br5+ atom. The N–Br bond length is 1.82 Å. Br5+ is bonded in a water-like geometry to two N+1.67- atoms.

Materials Data on CoBrN5O4 by Materials Project

CoN3(NO2)2Br crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four hydrobromic acid molecules, eight nitrous acid molecules, and four CoN3 clusters. In each CoN3 cluster, Co2+ is bonded in a distorted trigonal planar geometry to three N+0.20+ atoms. There are a spread of Co–N bond distances ranging from 1.53–1.81 Å. There are three inequivalent N+0.20+ sites. In the first N+0.20+ site, N+0.20+ is bonded in a single-bond geometry to one Co2+ atom. In the second N+0.20+ site, N+0.20+ is bonded in a single-bond geometry to one Co2+ atom. In the third N+0.20+ site, N+0.20+ is bonded in a single-bond geometry to one Co2+ atom.

Materials Data on CoBr2N6O by Materials Project

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.
