Hexakis(1-methyl-1H-imidazole-N³)cobalt(II) dibromide dihydrate

R. Yao

Abstract: The asymmetric unit of the title compound, [Co(C₄H₆N₂)₆]Br₂·2H₂O, contains one-half of the centrosymmetric cation, one Br atom and one water molecule. The Co^II atom, lying on an inversion center, has a distorted octahedral geometry, defined by six N atoms from six 1-methylimidazole ligands. In the crystal structure, intra- and intermolecular O-HBr hydrogen bonds link pairs of uncoordinated water molecules and bromide anions.
