The compound described by (Be2Cl5)2N2 is Cubic Laves structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of sixteen ammonia atoms and eight Be2Cl5 clusters. In each Be2Cl5 cluster, Be(1) is bonded to one Cl(2) and three equivalent Cl(1) atoms to form corner-sharing BeCl4 tetrahedra. There are two inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a water-like geometry to two equivalent Be(1) atoms. In the second Cl site, Cl(2) is bonded in a single-bond geometry to one Be(1) atom. is represented by the CIF card [CIF]
