Cr Cu Cu Re
CrReCu2 crystallizes in the monoclinic Cm space group. Cr(1) is bonded in a 10-coordinate geometry to two equivalent Re(1), four equivalent Cu(1), and four equivalent Cu(2) atoms. There is one shorter (2.46 Å) and one longer (2.56 Å) Cr(1)-Re(1) bond length. There are a spread of Cr(1)-Cu(1) bond distances ranging from 2.15-2.89 Å. There are a spread of Cr(1)-Cu(2) bond distances ranging from 2.10-2.85 Å. Re(1) is bonded in a 4-coordinate geometry to two equivalent Cr(1), one Cu(1), and one Cu(2) atom. The Re(1)-Cu(1) bond length is 2.34 Å. The Re(1)-Cu(2) bond length is 2.34 Å. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 1-coordinate geometry to four equivalent Cr(1) and one Re(1) atom. In the second Cu site, Cu(2) is bonded in a 1-coordinate geometry to four equivalent Cr(1) and one Re(1) atom.
