Abstract
The structure of [Pb3(OH)4Co(NO2)3](NO3)(NO2)×2H2O is determined by single crystal X-ray diffraction. The crystallographic characteristics are as follows: a = 8.9414(4) Å, b = 14.5330(5) Å, c = 24.9383(9) Å, V = 3240.6(2) Å3, space group Pbca , Z = 8. The Co(III) atoms have a slightly distorted octahedral coordination formed by three nitrogen atoms belonging to nitro groups (Co-Nav is 1.91 Å) and three oxygen atoms belonging to hydroxyl groups (Co-Oav is 1.93 Å). The hydroxyl groups act as m3-bridges between the metal atoms. The geometric characteristics are analyzed and the packing motif is determined.
