Y In In Cl
YIn2Cl crystallizes in the trigonal R3m space group. Y(1) is bonded in a distorted linear geometry to one In(1), three equivalent In(2), and one Cl(1) atom. The Y(1)-In(1) bond length is 2.06 Å. All Y(1)-In(2) bond lengths are 3.00 Å. The Y(1)-Cl(1) bond length is 2.06 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded to one Y(1), one In(2), and three equivalent Cl(1) atoms to form distorted InYInCl3 trigonal bipyramids that share corners with six equivalent In(1)YInCl3 trigonal bipyramids and corners with three equivalent In(2)Y3In trigonal pyramids. The In(1)-In(2) bond length is 2.06 Å. All In(1)-Cl(1) bond lengths are 3.00 Å. In the second In site, In(2) is bonded to three equivalent Y(1) and one In(1) atom to form InY3In trigonal pyramids that share corners with three equivalent In(1)YInCl3 trigonal bipyramids and corners with six equivalent In(2)Y3In trigonal pyramids. Cl(1) is bonded in a distorted single-bond geometry to one Y(1) and three equivalent In(1) atoms.
