Di -μazido-k⁴ N:N-bis-[(azido-kN)(2,9-dimethyl-1,10- phenanthroline-k² N,N′)nickel(II)]

The title complex, [Ni2(N3)4(C14H12N2)2], is a centrosymmetric dimer in which each Ni^II atom is coordinated by five N atoms (two from a 2,9-dimethyl-1,10-phenanthroline ligand, two from the bridging azide group and one from the terminal azide) in a slightly distorted square-pyramidal geometry. The Ni⋯Ni distance is 3.2532 (9) Å. In the crystal structure, mol-ecules are linked into one-dimensional chains by C - H⋯N hydrogen bonds and π-π stacking inter-actions [π-π interaction distance = 3.6215 (16) Å].
