Co B B Sb
CoB2Sb crystallizes in the triclinic P1 space group. Co(1) is bonded in a single-bond geometry to one B(1), one B(2), and one Sb(1) atom. The Co(1)-B(1) bond length is 0.24 Å. The Co(1)-B(2) bond length is 2.24 Å. The Co(1)-Sb(1) bond length is 1.95 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a single-bond geometry to one Co(1), two equivalent B(2), and one Sb(1) atom. There is one shorter (2.19 Å) and one longer (2.30 Å) B(1)-B(2) bond length. The B(1)-Sb(1) bond length is 1.88 Å. In the second B site, B(2) is bonded in a 5-coordinate geometry to one Co(1), two equivalent B(1), and two equivalent Sb(1) atoms. There is one shorter (2.31 Å) and one longer (2.37 Å) B(2)-Sb(1) bond length. Sb(1) is bonded in a 4-coordinate geometry to one Co(1), one B(1), and two equivalent B(2) atoms.
