YGaN2 crystallizes in the monoclinic P2_1/c space group. Y(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. Ga(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing GaN4 trigonal pyramids. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 5-coordinate geometry to three equivalent Y(1) and two equivalent Ga(1) atoms. In the second N site, N(2) is bonded in a 5-coordinate geometry to three equivalent Y(1) and two equivalent Ga(1) atoms.
YGaN2 crystallizes in the monoclinic P2_1/c space group. Y(1) is bonded in a 6-coordinate geometry to three equivalent N(1) and three equivalent N(2) atoms. There are a spread of Y(1)-N(1) bond distances ranging from 2.31-2.68 Å. There are a spread of Y(1)-N(2) bond distances ranging from 2.30-2.78 Å. Ga(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing GaN4 trigonal pyramids. There is one shorter (1.95 Å) and one longer (2.08 Å) Ga(1)-N(1) bond length. Both Ga(1)-N(2) bond lengths are 1.96 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 5-coordinate geometry to three equivalent Y(1) and two equivalent Ga(1) atoms. In the second N site, N(2) is bonded in a 5-coordinate geometry to three equivalent Y(1) and two equivalent Ga(1) atoms.
