Structure of Λ(δλλ)-[Co(en)3]I3(I)2.

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. © Kollitz et al. 2021.
