CaGaGeH crystallizes in the trigonal P3m1 space group. Ca(1) is bonded in a distorted trigonal planar geometry to three equivalent Ge(1) and three equivalent H(1) atoms. Ga(1) is bonded in a distorted single-bond geometry to three equivalent Ge(1) and one H(1) atom. Ge(1) is bonded in a 6-coordinate geometry to three equivalent Ca(1) and three equivalent Ga(1) atoms. H(1) is bonded to three equivalent Ca(1) and one Ga(1) atom to form corner-sharing HCa3Ga trigonal pyramids.
