Structure of Λ(δλλ)-[Co(en)3]I3(I) 2

Abstract

The structure of tris(ethane-1,2-diamine-κ2 N,N')cobalt(III) bis(iodide) triiodide, [Co(C2H8N2)3]I3(I)2, at 120 K has orthorhombic (P212121) symmetry. The diamine nitrogen atoms form N-H⋯I hydrogen bonds throughout the lattice, resulting in a three-dimensional network, which involves the iodide and all atoms in the triiodide anions.
