Co Co B P
Co2BP crystallizes in the monoclinic Pm space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to one Co(2), four equivalent B(1), and four equivalent P(1) atoms. The Co(1)-Co(2) bond length is 2.18 Å. There are two shorter (1.92 Å) and two longer (2.32 Å) Co(1)-B(1) bond lengths. There are two shorter (2.38 Å) and two longer (2.58 Å) Co(1)-P(1) bond lengths. In the second Co site, Co(2) is bonded in a 4-coordinate geometry to one Co(1), two equivalent B(1), and two equivalent P(1) atoms. Both Co(2)-B(1) bond lengths are 2.06 Å. Both Co(2)-P(1) bond lengths are 2.21 Å. B(1) is bonded in a 7-coordinate geometry to two equivalent Co(2), four equivalent Co(1), and one P(1) atom. The B(1)-P(1) bond length is 2.06 Å. P(1) is bonded in a 5-coordinate geometry to two equivalent Co(2), four equivalent Co(1), and one B(1) atom.
