Materials Data on GaTeCl by Materials Project
GaTeCl crystallizes in the orthorhombic Pnnm space group. The structure is two-dimensional and consists of two GaTeCl sheets oriented in the (0, 0, 1) direction. Ga3+ is bonded to three equivalent Te2- and one Cl1- atom to form distorted corner-sharing GaTe3Cl tetrahedra. There are one shorter (2.67 Å) and two longer (2.69 Å) Ga–Te bond lengths. The Ga–Cl bond length is 2.20 Å. Te2- is bonded in a 5-coordinate geometry to three equivalent Ga3+ and two equivalent Cl1- atoms. Both Te–Cl bond lengths are 3.84 Å. Cl1- is bonded in a single-bond geometry to one Ga3+ and two equivalent Te2- atoms.
