Y In In Br
YIn2Br crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two YIn2Br clusters. Y(1) is bonded in a single-bond geometry to one In(2) atom. The Y(1)-In(2) bond length is 2.10 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a single-bond geometry to one Br(1) atom. The In(1)-Br(1) bond length is 2.77 Å. In the second In site, In(2) is bonded in a distorted single-bond geometry to one Y(1) and one Br(1) atom. The In(2)-Br(1) bond length is 0.76 Å. Br(1) is bonded in a single-bond geometry to one In(1) and one In(2) atom.
