Sr Cr Cr Mo
SrMoCr2 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 5-coordinate geometry to four equivalent Mo(1) and one Cr(2) atom. There are a spread of Sr(1)-Mo(1) bond distances ranging from 2.84-2.96 Å. The Sr(1)-Cr(2) bond length is 3.06 Å. Mo(1) is bonded in a distorted single-bond geometry to four equivalent Sr(1) and one Cr(1) atom. The Mo(1)-Cr(1) bond length is 1.76 Å. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a single-bond geometry to one Mo(1) and four equivalent Cr(2) atoms. There are a spread of Cr(1)-Cr(2) bond distances ranging from 2.38-2.52 Å. In the second Cr site, Cr(2) is bonded in a 5-coordinate geometry to one Sr(1) and four equivalent Cr(1) atoms.
