description: Cu3P15I2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Cu+1.67+ sites. In the first Cu+1.67+ site, Cu+1.67+ is bonded to three P+0.20- and one I1- atom to form CuP3I tetrahedra that share corners with two CuP3I tetrahedra, corners with two PCuP3 tetrahedra, and a cornercorner with one PCu2P2 trigonal pyramid. There are a spread of Cu–P bond distances ranging from 2.29–2.32 Å. The Cu–I bond length is 2.61 Å. In the second Cu+1.67+ site, Cu+1.67+ is bonded to two P+0.20- and two I1- atoms to form CuP2I2 tetrahedra that share a cornercorner with one PCuP3 tetrahedra and corners with two CuP3I tetrahedra. Both Cu–P bond lengths are 2.32 Å. There are one shorter (2.68 Å) and one longer (2.69 Å) Cu–I bond lengths.
