title: A redetermination of bis-(5,5'-diethyl-barbiturato)bis-(imidazole)cobalt(II).
abstract: The title complex, [Co(C(8)H(12)N(2)O(3))(2)(C(3)H(4)N(2))(2)], whose structure was first determined by Wang & Craven [(1971). J. Chem. Soc. D, pp. 290-291], has been redetermined with improved precision. A crystallographic twofold rotation axis passes through the Co atom, which is tetrahedrally coordinated by two N atoms from two barbital ligands and two N atoms from two imidazole ligands. The mol-ecules are self-assembled via inter-molecular N-H⋯O hydrogen-bonding inter-actions into a supra-molecular network.
