Materials Data on CaGaSnH by Materials Project
CaGaSnH crystallizes in the trigonal P3m1 space group. The structure is three-dimensional. Ca is bonded in a distorted trigonal planar geometry to three equivalent Sn and three equivalent H atoms. All Ca–Sn bond lengths are 3.37 Å. All Ca–H bond lengths are 2.54 Å. Ga is bonded in a distorted single-bond geometry to three equivalent Sn and one H atom. All Ga–Sn bond lengths are 2.67 Å. The Ga–H bond length is 1.73 Å. Sn is bonded in a 6-coordinate geometry to three equivalent Ca and three equivalent Ga atoms. H is bonded to three equivalent Ca and one Ga atom to form corner-sharing HCa3Ga trigonal pyramids.
