| Abstract: | Complex [Ni(NO3)2(3,5-lutidine)3] (3,5-lutidine, 3,5-Lut-C7H9N) was synthesized, and its crystal structure was determined. Complex crystals are monoclinic: space group Cc, a = 14.445(1) Å, b = 10.024(1) Å, c = 17.607(1) Å, β = 108.96(1)°, V = 2411(1) Å3, ρcalcd = 2.389 g/cm3, Z = 4. The structure is built of discrete neutral complexes [Ni(3,5-Lut)3(NO3)2]. The coordination sphere of Ni2+ ions is a disordered octahedron, which consists of three crystallographically nonequivalent lutidine ligands (Ni-N, 2.059–2.124 Å) and two oxygen ions of the two nitrate ions (Ni-O, 2.047–2.258 Å). |
