Ca(GaN)2 crystallizes in the monoclinic P2_1/c space group. Ca(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in an L-shaped geometry to one N(1) and one N(2) atom. In the second Ga site, Ga(2) 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 to two equivalent Ca(1), one Ga(1), and two equivalent Ga(2) atoms to form a mixture of distorted corner and edge-sharing NCa2Ga3 trigonal bipyramids. In the second N site, N(2) is bonded to two equivalent Ca(1), one Ga(1), and two equivalent Ga(2) atoms to form a mixture of distorted corner and edge-sharing NCa2Ga3 trigonal bipyramids.
Ca(GaN)2 crystallizes in the monoclinic P2_1/c space group. Ca(1) is bonded in a 4-coordinate geometry to two equivalent N(1) and two equivalent N(2) atoms. There is one shorter (2.46 Å) and one longer (2.70 Å) Ca(1)-N(1) bond length. Both Ca(1)-N(2) bond lengths are 2.42 Å. There are two inequivalent Ga sites. In the first Ga site, Ga(1) is bonded in an L-shaped geometry to one N(1) and one N(2) atom. The Ga(1)-N(1) bond length is 2.01 Å. The Ga(1)-N(2) bond length is 2.06 Å. In the second Ga site, Ga(2) 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 (1.99 Å) and one longer (2.00 Å) Ga(2)-N(1) bond length. There is one shorter (1.98 Å) and one longer (2.02 Å) Ga(2)-N(2) bond length. There are two inequivalent N sites.
