Figure 2
Crystal structures of the [Bi2O2(OH)(NO3)] polymorphs. Strong Bi—O bonds (2.20–2.62 Å) are shown as black lines, weaker Bi—O bonds (2.80–3.00 Å) as grey lines; colour code for both structures: Bi1 blue, Bi2 light blue, N1 purple, O2 associated with the OH group green, all other O atoms white; the O2⋯O hydrogen bond is displayed with green lines. (a) The Pna21 structure of Bi2O2(OH)](NO3)-II with atoms at the 97% probability level; symmetry codes refer to Table 1 ![[link]](../../../../../../logos/arrows/e_arr.gif){kind=small} and (b) the Cmc21 structure of [Bi2O2(OH)](NO3)-I (Henry et al., 2005) with atoms shown as spheres of arbitrary radius. In the inset, the nitrate group is rotated by 60° to show the disorder present in Bi2O2(OH)](NO3)-I. |
