Zn4SnN4 crystallizes in the triclinic P-1 space group. There are four inequivalent Zn sites. In the first Zn site, Zn(1) is bonded in a trigonal planar geometry to one N(2), one N(3), and one N(4) atom. In the second Zn site, Zn(2) is bonded in a distorted trigonal planar geometry to one N(3) and two equivalent N(2) atoms. In the third Zn site, Zn(3) is bonded in a distorted trigonal planar geometry to one N(1) and two equivalent N(4) atoms. In the fourth Zn site, Zn(4) is bonded in a distorted trigonal planar geometry to one N(3) and two equivalent N(1) atoms. Sn(1) is bonded in a tetrahedral geometry to one N(1), one N(2), one N(3), and one N(4) atom. There are four inequivalent N sites. In the first N site, N(1) is bonded to one Zn(3), two equivalent Zn(4), and one Sn(1) atom to form a mixture of corner and edge-sharing NZn3Sn tetrahedra. In the second N site, N(2) is bonded to one Zn(1), two equivalent Zn(2), and one Sn(1) atom to form a mixture of corner and edge-sharing NZn3Sn tetrahedra. In the third N site, N(3) is bonded to one Zn(1), one Zn(2), one Zn(4), and one Sn(1) atom to form corner-sharing NZn3Sn tetrahedra. In the fourth N site, N(4) is bonded to one Zn(1), two equivalent Zn(3), and one Sn(1) atom to form a mixture of corner and edge-sharing NZn3Sn tetrahedra.
