Ba Be Be Ge
BaBe2Ge is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two BaBe2Ge clusters. Ba(1) is bonded in an L-shaped geometry to two equivalent Be(1) atoms. Both Ba(1)-Be(1) bond lengths are 1.36 Å. Be(1) is bonded in an L-shaped geometry to one Ba(1) and one Ge(1) atom. The Be(1)-Ge(1) bond length is 1.36 Å. Ge(1) is bonded in an L-shaped geometry to two equivalent Be(1) atoms.
