Sr Co Co Os
SrOsCo2 crystallizes in the monoclinic Pm space group. Sr(1) is bonded in a distorted single-bond geometry to one Os(1) and four equivalent Co(1) atoms. The Sr(1)-Os(1) bond length is 1.44 Å. There are two shorter (2.51 Å) and two longer (2.79 Å) Sr(1)-Co(1) bond lengths. Os(1) is bonded in a single-bond geometry to one Sr(1) and four equivalent Co(1) atoms. There are two shorter (2.51 Å) and two longer (2.79 Å) Os(1)-Co(1) bond lengths. Co(1) is bonded in a 5-coordinate geometry to two equivalent Sr(1), two equivalent Os(1), and one Co(1) atom. The Co(1)-Co(1) bond length is 1.66 Å.
