Materials Data on GaClO by Materials Project
GaOCl crystallizes in the orthorhombic Pca2_1 space group. The structure is two-dimensional and consists of one GaOCl sheet oriented in the (0, 0, 1) direction. Ga3+ is bonded to three equivalent O2- and one Cl1- atom to form corner-sharing GaClO3 tetrahedra. There is one shorter (1.88 Å) and two longer (1.91 Å) Ga–O bond length. The Ga–Cl bond length is 2.12 Å. O2- is bonded in a trigonal planar geometry to three equivalent Ga3+ atoms. Cl1- is bonded in a single-bond geometry to one Ga3+ atom.
