title: Diazido-bis(2,2'-biimidazole)cobalt(II).
abstract: In the title compound, [Co(N(3))(2)(C(6)H(6)N(4))(2)], the Co(II) atom lies on a centre of inversion and is bonded to two azide ions and two bidentate 2,2'-biimidizole ligands, giving a slightly distorted octa-hedral CoN(6) coordination geometry. In the crystal structure, inter-molecular N-H⋯N hydrogen bonds exist between the 2,2'-biimidizole ligands and the azide ions, linking the complexes into sheets.
