SrWCo2 crystallizes in the monoclinic Cm space group. Sr(1) is bonded in a 10-coordinate geometry to four equivalent Sr(1), four equivalent W(1), and two equivalent Co(1) atoms. All Sr(1)-Sr(1) bond lengths are 3.10 Å. There are a spread of Sr(1)-W(1) bond distances ranging from 3.41-3.69 Å. There is one shorter (3.66 Å) and one longer (3.74 Å) Sr(1)-Co(1) bond length. W(1) is bonded in a single-bond geometry to four equivalent Sr(1), one Co(2), and four equivalent Co(1) atoms. The W(1)-Co(2) bond length is 0.22 Å. There are a spread of W(1)-Co(1) bond distances ranging from 2.15-2.58 Å. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 10-coordinate geometry to two equivalent Sr(1), four equivalent W(1), and four equivalent Co(2) atoms. There are a spread of Co(1)-Co(2) bond distances ranging from 2.07-2.51 Å. In the second Co site, Co(2) is bonded in a single-bond geometry to one W(1) and four equivalent Co(1) atoms.
