Be Be Be Be Ge Os
Be3OsBeGe is alpha As structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three Be3Os clusters and three BeGe clusters. In each Be3Os cluster, Be(1) is bonded in a distorted single-bond geometry to one Os(1) atom. The Be(1)-Os(1) bond length is 1.45 Å. Os(1) is bonded in a trigonal non-coplanar geometry to three equivalent Be(1) atoms. In each BeGe cluster, Be(2) is bonded in a single-bond geometry to one Ge(1) atom. The Be(2)-Ge(1) bond length is 1.59 Å. Ge(1) is bonded in a distorted single-bond geometry to one Be(2) atom.
