The compound described by Sr2C(NCl)2 crystallizes in the monoclinic C2/m space group. Sr(1) is bonded in a 7-coordinate geometry to three equivalent N(1) and four equivalent Cl(1) atoms. C(1) is bonded in a linear geometry to two equivalent N(1) atoms. N(1) is bonded to three equivalent Sr(1) and one C(1) atom to form distorted NSr3C tetrahedra that share corners with three equivalent N(1)Sr3C tetrahedra, corners with ten equivalent Cl(1)Sr4 tetrahedra,  an edgeedge with one Cl(1)Sr4 tetrahedra, and edges with two equivalent N(1)Sr3C tetrahedra. Cl(1) is bonded to four equivalent Sr(1) atoms to form ClSr4 tetrahedra that share corners with six equivalent Cl(1)Sr4 tetrahedra, corners with ten equivalent N(1)Sr3C tetrahedra,  an edgeedge with one N(1)Sr3C tetrahedra, and edges with three equivalent Cl(1)Sr4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
