Co Co Os Au
OsCo2Au crystallizes in the triclinic P1 space group. Os(1) is bonded in a 3-coordinate geometry to one Co(1), two equivalent Co(2), and two equivalent Au(1) atoms. The Os(1)-Co(1) bond length is 1.62 Å. There is one shorter (0.91 Å) and one longer (1.82 Å) Os(1)-Co(2) bond length. There is one shorter (2.39 Å) and one longer (2.82 Å) Os(1)-Au(1) bond length. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 1-coordinate geometry to one Os(1) and two equivalent Au(1) atoms. There is one shorter (2.64 Å) and one longer (2.75 Å) Co(1)-Au(1) bond length. In the second Co site, Co(2) is bonded in a distorted single-bond geometry to two equivalent Os(1) and two equivalent Au(1) atoms. There is one shorter (2.26 Å) and one longer (2.99 Å) Co(2)-Au(1) bond length. Au(1) is bonded in a 8-coordinate geometry to two equivalent Os(1), two equivalent Co(1), two equivalent Co(2), and two equivalent Au(1) atoms. Both Au(1)-Au(1) bond lengths are 2.73 Å.
