Tris[2-(1H-imidazol-2-yl)imidazol-1-ido]cobalt(III)
Abstract
In the title compound, [Co(C6H5N4)3], the CoIII atom adopts a distorted octahedral CoN6 coordination geometry, arising from three N,N′-bidentate deprotonated 2,2′-biimidazole ligands. The dihedral angles between the five-membered rings of the ligands are 4.1 (2), 9.4 (2) and 10.5 (2)°. In the crystal, molecules are linked by N—H...N hydrogen bonds, generating a layered network lying in (11overline{1}).
