Sr Sr Re W
Sr2WRe crystallizes in the monoclinic Pm space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a single-bond geometry to one W(1) and one Re(1) atom. The Sr(1)-W(1) bond length is 0.59 Å. The Sr(1)-Re(1) bond length is 3.78 Å. In the second Sr site, Sr(2) is bonded in a distorted single-bond geometry to one W(1) and one Re(1) atom. The Sr(2)-W(1) bond length is 2.66 Å. The Sr(2)-Re(1) bond length is 3.78 Å. W(1) is bonded in a single-bond geometry to one Sr(1) and one Sr(2) atom. Re(1) is bonded to one Sr(1), one Sr(2), and four equivalent Re(1) atoms to form a mixture of edge and corner-sharing ReSr2Re4 octahedra. The corner-sharing octahedra are not tilted. All Re(1)-Re(1) bond lengths are 2.87 Å.
