Materials Data on BeClO by Materials Project
(BeO)2Cl2 crystallizes in the trigonal R-3m space group. The structure is two-dimensional and consists of six BeO sheets oriented in the (0, 0, 1) direction and six Cl2 sheets oriented in the (0, 0, 1) direction. In each BeO sheet, Be is bonded in a trigonal planar geometry to three equivalent O atoms. All Be–O bond lengths are 1.56 Å. O is bonded in a trigonal planar geometry to three equivalent Be atoms. In each Cl2 sheet, Cl is bonded in a hexagonal planar geometry to six equivalent Cl atoms. All Cl–Cl bond lengths are 2.71 Å.
