Ca(C2N3)2 crystallizes in the monoclinic C2/c space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent N(2), two equivalent N(3), and four equivalent N(1) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. In the second C site, C(2) is bonded in a linear geometry to one N(2) and one N(3) atom. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to two equivalent Ca(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted bent 120 degrees geometry to one Ca(1), one C(1), and one C(2) atom. In the third N site, N(3) is bonded in a distorted bent 150 degrees geometry to one Ca(1) and one C(2) atom.
Ca(C2N3)2 crystallizes in the monoclinic C2/c space group. Ca(1) is bonded in a 8-coordinate geometry to two equivalent N(2), two equivalent N(3), and four equivalent N(1) atoms. Both Ca(1)-N(2) bond lengths are 2.97 Å. Both Ca(1)-N(3) bond lengths are 2.46 Å. There are two shorter (2.52 Å) and two longer (2.66 Å) Ca(1)-N(1) bond lengths. There are two inequivalent C sites. In the first C site, C(1) is bonded in a linear geometry to one N(1) and one N(2) atom. The C(1)-N(1) bond length is 1.18 Å. The C(1)-N(2) bond length is 1.29 Å. In the second C site, C(2) is bonded in a linear geometry to one N(2) and one N(3) atom. The C(2)-N(2) bond length is 1.31 Å. The C(2)-N(3) bond length is 1.18 Å.
