Sažetak
The title compound, [Ni(N3)2(C6H6N2O)2], was obtained as the first crystalline product from the reaction of Ni(NO3)2.6H2O, picolinamide and NaN3 in aqueous media. After a few days in the mother liquor, crystals of the cis isomer transformed into the trans isomer [Đaković and Popović (2007). Acta Cryst. C63, m507-m509]. The Ni atom exhibits a distorted octahedral environment and contains two azide ions and two planar N, O-chelating picolinamide ligands, all cis related. The dihedral angle between the two chelate rings is 82.43(7)o. Pairs of molecules are linked by N-H...N hydrogen bonds into R22(16) dimers, which are further packed into a three-dimensional framework by C(6) and C(8) chains by N-H...N hydrogen bonds.
