The compound described by Sr(C2N3)2 crystallizes in the monoclinic C2/c space group. Sr(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 distorted single-bond geometry to two equivalent Sr(1) and one C(1) atom. In the second N site, N(2) is bonded in a distorted bent 120 degrees geometry to one Sr(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 Sr(1) and one C(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
