Sr Cr Cr In
SrCr2In is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two SrCr2In clusters. Sr(1) is bonded in a distorted L-shaped geometry to two equivalent Cr(1) atoms. Both Sr(1)-Cr(1) bond lengths are 1.75 Å. Cr(1) is bonded in a 2-coordinate geometry to one Sr(1) and one In(1) atom. The Cr(1)-In(1) bond length is 1.75 Å. In(1) is bonded in a distorted L-shaped geometry to two equivalent Cr(1) atoms.
