A novel cation-stabilized iodocuprate, named {CuI3](1,6-bpx)}1), [1,6-bpx = 1,6-bis(pyridinium)xylol] have been constructed from mixtures of bis(pyridinium) xylol and cuprous iodide in acetonitrile solution. Compound 1 was characterized by elemental analysis, IR spectra and X-ray crystallography. The dianions of 1 have planar triangular geometry with each halide atom being bound to the central trigonally coordinated copper atom. The chemical and thermal properties of 1 along with 1,6-bpx have also been investigated. [ABSTRACT FROM AUTHOR]
