BGe crystallizes in the monoclinic P2 space group. B(1) is bonded in a 4-coordinate geometry to five equivalent Ge(1) atoms. There are a spread of B(1)-Ge(1) bond distances ranging from 1.96-2.73 Å. Ge(1) is bonded in a 7-coordinate geometry to five equivalent B(1) and two equivalent Ge(1) atoms. There is one shorter (2.51 Å) and one longer (2.79 Å) Ge(1)-Ge(1) bond length.
