Tris(ethane-1,2-diamine-κ2 N,N′)cobalt(III) carbonate iodide tetra­hydrate

Abstract

The title compound, [Co(C2H8N2)3](CO3)I·4H2O, crystallizes with a [Co(en)3]3+ cation (en is ethane-1,2-diamine), CO3 2− and I− anions and four water mol­ecules in the asymmetric unit. In the cation, the three rings formed by the ethyl­enediamine units and the CoIII metal ion are in slightly distorted twist conformations. Numerous O—H⋯O, N—H⋯O, N—H⋯I and O—H⋯I inter­molecular hydrogen bonds between the cation and two anions in concert with the four water mol­ecules dominate the crystal packing and create a supra­molecular infinite three-dimensional framework
