Cd Si Si P
PCd(Si)2 is High Pressure Cadmuum Telluride structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two disilane molecules and two PCd clusters. In each PCd cluster, Cd(1) is bonded in a single-bond geometry to one P(1) atom. The Cd(1)-P(1) bond length is 0.71 Å. P(1) is bonded in a single-bond geometry to one Cd(1) atom.
