SrCrCu2 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 8-coordinate geometry to four equivalent Cu(1) and four equivalent Cu(2) atoms. There are a spread of Sr(1)-Cu(1) bond distances ranging from 2.61-3.17 Å. There are a spread of Sr(1)-Cu(2) bond distances ranging from 2.61-3.17 Å. Cr(1) is bonded in a 8-coordinate geometry to four equivalent Cu(1) and four equivalent Cu(2) atoms. There are a spread of Cr(1)-Cu(1) bond distances ranging from 2.50-3.08 Å. There are a spread of Cr(1)-Cu(2) bond distances ranging from 2.53-3.11 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Cr(1) atoms. In the second Cu site, Cu(2) is bonded in a 8-coordinate geometry to four equivalent Sr(1) and four equivalent Cr(1) atoms.
