Sr6GaN5 crystallizes in the hexagonal P6_3/mcm space group. Sr(1) is bonded in a 5-coordinate geometry to two equivalent N(2) and three equivalent N(1) atoms. Ga(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(2) is bonded to six equivalent Sr(1) atoms to form distorted edge-sharing NSr6 octahedra. In the second N site, N(1) is bonded in a 7-coordinate geometry to six equivalent Sr(1) and one Ga(1) atom.
Sr6GaN5 crystallizes in the hexagonal P6_3/mcm space group. Sr(1) is bonded in a 5-coordinate geometry to two equivalent N(2) and three equivalent N(1) atoms. Both Sr(1)-N(2) bond lengths are 2.60 Å. There is one shorter (2.65 Å) and two longer (2.94 Å) Sr(1)-N(1) bond lengths. Ga(1) is bonded in a trigonal planar geometry to three equivalent N(1) atoms. All Ga(1)-N(1) bond lengths are 1.91 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded to six equivalent Sr(1) atoms to form distorted edge-sharing NSr6 octahedra. In the second N site, N(1) is bonded in a 7-coordinate geometry to six equivalent Sr(1) and one Ga(1) atom.
