Structure of Λ(δλλ)-[Co(en)3]I3(I)2

Abstract

The structure of tris-(ethane-1,2-di-amine-κ² N,N')cobalt(III) bis-(iodide) triiodide, [Co(C₂H₈N₂)₃]I₃(I)₂, at 120 K has ortho-rhom-bic (P2₁2₁2₁) symmetry. The di-amine nitro-gen 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.

Keywords: chiral coordination; cobalt coordination; crystal structure.
