Y Y In Cu
Y2CuIn crystallizes in the monoclinic Cm space group. Y(1) is bonded in a single-bond geometry to one Cu(1) and three equivalent In(1) atoms. The Y(1)-Cu(1) bond length is 1.39 Å. There are a spread of Y(1)-In(1) bond distances ranging from 2.73-3.46 Å. Cu(1) is bonded in a water-like geometry to two equivalent Y(1) and two equivalent In(1) atoms. There is one shorter (2.35 Å) and one longer (3.16 Å) Cu(1)-In(1) bond length. In(1) is bonded in a 8-coordinate geometry to six equivalent Y(1) and two equivalent Cu(1) atoms.
