The compound described by Sn(PbN)4 crystallizes in the triclinic P-1 space group. There are four inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a 3-coordinate geometry to one N(1), one N(2), and one N(4) atom. In the second Pb site, Pb(2) is bonded in a distorted T-shaped geometry to one N(3) and two equivalent N(2) atoms. In the third Pb site, Pb(3) is bonded in a 3-coordinate geometry to one N(3) and two equivalent N(1) atoms. In the fourth Pb site, Pb(4) is bonded in a 3-coordinate geometry to one N(3) and two equivalent N(4) atoms. Sn(1) is bonded in a distorted trigonal pyramidal 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 Pb(1), two equivalent Pb(3), and one Sn(1) atom to form a mixture of edge and corner-sharing NSnPb3 tetrahedra. In the second N site, N(2) is bonded in a 4-coordinate geometry to one Pb(1), two equivalent Pb(2), and one Sn(1) atom. In the third N site, N(3) is bonded to one Pb(2), one Pb(3), one Pb(4), and one Sn(1) atom to form a mixture of distorted edge and corner-sharing NSnPb3 tetrahedra. In the fourth N site, N(4) is bonded to one Pb(1), two equivalent Pb(4), and one Sn(1) atom to form a mixture of edge and corner-sharing NSnPb3 trigonal pyramids. is represented by the Crystallographic Information File (CIF) [CIF]
