Y In In As
YIn2As crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YIn2As clusters. Y(1) is bonded in a bent 150 degrees geometry to one In(1) and one In(2) atom. The Y(1)-In(1) bond length is 1.15 Å. The Y(1)-In(2) bond length is 1.15 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a single-bond geometry to one Y(1) atom. In the second In site, In(2) is bonded in a distorted bent 150 degrees geometry to one Y(1) and one As(1) atom. The In(2)-As(1) bond length is 1.00 Å. As(1) is bonded in a single-bond geometry to one In(2) atom.
