ResumoThe reaction of antimony(III)chloride and antimony(V)chloride in acetonitrile in the presence of the azamacrocyclic ligand Me3[9]aneN3 provides the golden-yellow ionic compound [SbCl2(Me3[9]aneN3][SbCl6]. X-ray structural characterization reveals the cation as five-coordinate with Ψ-octahedral metal geometry featuring a cis-SbCl2+ unit coordinated to the three donor nitrogen atoms of the ligand (fac) and a stereochemically active lone pair occupying the sixth site in a trans-position to a ring nitrogen atom.
