Sr Co Co W
SrWCo2 crystallizes in the monoclinic Pm space group. Sr(1) is bonded in a 1-coordinate geometry to one W(1) and four equivalent Co(1) atoms. The Sr(1)-W(1) bond length is 1.70 Å. There are two shorter (2.41 Å) and two longer (2.67 Å) Sr(1)-Co(1) bond lengths. W(1) is bonded in a distorted single-bond geometry to one Sr(1) and four equivalent Co(1) atoms. There are two shorter (2.41 Å) and two longer (2.67 Å) W(1)-Co(1) bond lengths. Co(1) is bonded in a 5-coordinate geometry to two equivalent Sr(1), two equivalent W(1), and one Co(1) atom. The Co(1)-Co(1) bond length is 1.92 Å.
