Ba Ba Be W
BaBeBaW is Cubic alpha N2-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two barium;tungsten molecules and two BaBe clusters. In each BaBe cluster, Ba(1) is bonded in a single-bond geometry to one Be(1) atom. The Ba(1)-Be(1) bond length is 0.36 Å. Be(1) is bonded in a single-bond geometry to one Ba(1) atom.
