Mn B B Sb
MnB2Sb crystallizes in the triclinic P1 space group. Mn(1) is bonded in a linear geometry to one B(1), one B(2), and four equivalent Sb(1) atoms. The Mn(1)-B(1) bond length is 1.44 Å. The Mn(1)-B(2) bond length is 1.44 Å. There are a spread of Mn(1)-Sb(1) bond distances ranging from 3.11-3.22 Å. There are two inequivalent B sites. In the first B site, B(1) is bonded in a distorted water-like geometry to one Mn(1) and one B(2) atom. The B(1)-B(2) bond length is 0.37 Å. In the second B site, B(2) is bonded in a distorted water-like geometry to one Mn(1) and one B(1) atom. Sb(1) is bonded in a 6-coordinate geometry to four equivalent Mn(1) and two equivalent Sb(1) atoms. Both Sb(1)-Sb(1) bond lengths are 3.00 Å.
