Cu Cu Cu Te
Cu3Te is Ammonia-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two Cu3Te clusters. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a single-bond geometry to one Te(1) atom. The Cu(1)-Te(1) bond length is 0.21 Å. In the second Cu site, Cu(2) is bonded in a single-bond geometry to one Te(1) atom. The Cu(2)-Te(1) bond length is 0.19 Å. Te(1) is bonded in a trigonal non-coplanar geometry to one Cu(2) and two equivalent Cu(1) atoms.
