Iodidobis(1,10-phenanthroline)copper(II) perchlorate.

The title compound, [CuI(C12H8N2)2]ClO4, was prepared by a hydrothermal reaction at 453 K. The Cu atom has a slightly distorted trigonal–bipyramidal coordination geometry, pentacoordinated by four N atoms of two chelating 1,10-phenanthroline ligands and one I atom. There are supramolecular π–π interactions between neighbouring parallel pyridine rings, with a face-to-face distance of 3.51 (1) Å. [ABSTRACT FROM AUTHOR]
