Single crystal X-ray structure determination of green single crystals of trans-[Co(en)(2)Cl(2)](2)CdI(4) revealed that trans-[Co(en)(2)Cl(2)](+) has octahedral geometry around cobalt(III). Supramolecular hydrogen bonding networks [NH(en)+ center dot center dot center dot I(anion)(-)] in the second coordination sphere and electrostatic forces stabilize crystal lattice. This suggests that trans-[Co(en)(2)Cl(2)](+) is a promising anion receptor for tetraiodocadmate(II).
