Sr6Ga5N crystallizes in the trigonal R-3c space group. Sr(1) is bonded in a distorted single-bond geometry to two equivalent Ga(2), three equivalent Ga(1), and one N(1) atom. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to six equivalent Sr(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to six equivalent Sr(1) and three equivalent Ga(1) atoms. N(1) is bonded in an octahedral geometry to six equivalent Sr(1) atoms.
Sr6Ga5N crystallizes in the trigonal R-3c space group. Sr(1) is bonded in a distorted single-bond geometry to two equivalent Ga(2), three equivalent Ga(1), and one N(1) atom. There is one shorter (3.34 Å) and one longer (3.48 Å) Sr(1)-Ga(2) bond length. There are a spread of Sr(1)-Ga(1) bond distances ranging from 3.29-3.48 Å. The Sr(1)-N(1) bond length is 2.60 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in a 10-coordinate geometry to six equivalent Sr(1), two equivalent Ga(1), and two equivalent Ga(2) atoms. Both Ga(1)-Ga(1) bond lengths are 2.71 Å. Both Ga(1)-Ga(2) bond lengths are 2.70 Å. In the second Ga site, Ga(2) is bonded in a 9-coordinate geometry to six equivalent Sr(1) and three equivalent Ga(1) atoms. N(1) is bonded in an octahedral geometry to six equivalent Sr(1) atoms.
