A redetermination of bis(5,5'-diethylbarbiturato)bis(imidazole)cobalt(II)

R.-Z. Fan, P.-Z. Hong and W.-D. Song

Abstract: The title complex, [Co(C₈H₁₂N₂O₃)₂(C₃H₄N₂)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 molecules are self-assembled via intermolecular N-HO hydrogen-bonding interactions into a supramolecular network.
