B B Os Cl
OsB2Cl crystallizes in the triclinic P1 space group. Os(1) is bonded in a 3-coordinate geometry to two equivalent B(2) and two equivalent Cl(1) atoms. There is one shorter (2.01 Å) and one longer (2.43 Å) Os(1)-B(2) bond length. There is one shorter (1.99 Å) and one longer (2.07 Å) Os(1)-Cl(1) bond length. There are two inequivalent B sites. In the first B site, B(1) is bonded in a 2-coordinate geometry to one B(2) and two equivalent Cl(1) atoms. The B(1)-B(2) bond length is 0.79 Å. There is one shorter (2.01 Å) and one longer (2.43 Å) B(1)-Cl(1) bond length. In the second B site, B(2) is bonded in a 4-coordinate geometry to two equivalent Os(1), one B(1), and one Cl(1) atom. The B(2)-Cl(1) bond length is 2.37 Å. Cl(1) is bonded in a 5-coordinate geometry to two equivalent Os(1), one B(2), and two equivalent B(1) atoms.
