Materials Data on GaHCl2 by Materials Project
GaHCl2 is Protactinium structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four ac1o4jdr molecules. Ga3+ is bonded to one H1- and three Cl1- atoms to form distorted edge-sharing GaHCl3 tetrahedra. The Ga–H bond length is 1.53 Å. There are a spread of Ga–Cl bond distances ranging from 2.17–2.36 Å. H1- is bonded in a single-bond geometry to one Ga3+ atom. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in an L-shaped geometry to two equivalent Ga3+ atoms. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Ga3+ atom.
