Synthesis and crystal structure determinations of the bis-(5,5-diethylbarbiturato)-bisimidazole complexes of cobalt(II) and zinc(II)

Abstract

In the molecular structures of the bis-(5,5-diethylbarbiturato)-bisimidazole complexes of cobalt(II) and zinc(II) there is tetrahedral co-ordination of the metal atom by nitrogen atoms, and a conformation stabilized by C–H ⋯ O intramolecular interactions between almost coplanar pairs of imidazole and barbiturate rings.
