The crystal structure described by Sr2GaGeN crystallizes in the monoclinic P2_1/m space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded in a 3-coordinate geometry to two equivalent Ge(1) and three equivalent N(1) atoms. In the second Sr site, Sr(2) is bonded in a 2-coordinate geometry to three equivalent Ge(1) and two equivalent N(1) atoms. Ga(1) is bonded in a distorted single-bond geometry to two equivalent Ge(1) and one N(1) atom. Ge(1) is bonded in a 7-coordinate geometry to two equivalent Sr(1), three equivalent Sr(2), and two equivalent Ga(1) atoms. N(1) is bonded to two equivalent Sr(2), three equivalent Sr(1), and one Ga(1) atom to form distorted edge-sharing NSr5Ga octahedra. is represented by the Crystallographic Information File (CIF) [CIF]
