The structure described by Sn(C4N3)2 crystallizes in the orthorhombic Pmna space group. Sn(1) is bonded in an octahedral geometry to two equivalent N(2) and four equivalent N(1) atoms. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted linear geometry to one C(2) and one N(2) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one C(1) and two equivalent C(3) atoms. In the third C site, C(3) is bonded in a distorted linear geometry to one C(2) and one N(1) atom. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted linear geometry to one Sn(1) and one C(3) atom. In the second N site, N(2) is bonded in a distorted bent 150 degrees geometry to one Sn(1) and one C(1) atom. is represented by the CIF file [CIF]
