Bis(tetrapropylammonium) di-μ3-iodido-di-μ2-iodido-diiodidodipyridinetetracopper(I)

Abstract

The title compound, (C12H28N)2[Cu3.194I6(C5H5N)2] was prepared from reaction of copper powder, copper(I) oxide, hydroiodic acid, tetrapropylammonium iodide and pyridine under hydrothermal conditions. In the centrosymmetric Cu4I62− anion, one Cu site is in a trigonal-planar coordination while the second Cu site, which is only partially occupied [site occupancy of 0.5968 (16)], is surroundedby three iodine atoms and one pyridine molecule in a distorted tetrahedral coordination.
