The compound described by SnSiN2 crystallizes in the orthorhombic Ima2 space group. Sn(1) is bonded in a distorted T-shaped geometry to one N(1) and two equivalent N(2) atoms. Si(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing SiN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Sn(1) and two equivalent Si(1) atoms. In the second N site, N(2) is bonded to two equivalent Sn(1) and two equivalent Si(1) atoms to form distorted edge-sharing NSi2Sn2 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
