Sr2GeN2 crystallizes in the orthorhombic Cmce space group. There are two inequivalent Sr sites. In the first Sr site, Sr(1) is bonded to two equivalent N(2) and three equivalent N(1) atoms to form a mixture of distorted edge and corner-sharing SrN5 square pyramids. In the second Sr site, Sr(2) is bonded to two equivalent N(1) and three equivalent N(2) atoms to form a mixture of distorted edge and corner-sharing SrN5 trigonal bipyramids. Ge(1) is bonded in a bent 120 degrees geometry to one N(1) and one N(2) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Sr(2), three equivalent Sr(1), and one Ge(1) atom to form a mixture of edge and corner-sharing NSr5Ge octahedra. The corner-sharing octahedral tilt angles range from 8-59°. In the second N site, N(2) is bonded to two equivalent Sr(1), three equivalent Sr(2), and one Ge(1) atom to form a mixture of edge and corner-sharing NSr5Ge octahedra. The corner-sharing octahedral tilt angles range from 11-59°.
