The material structure described by V3Pb3N5 crystallizes in the triclinic P-1 space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one N(1), one N(5), and two equivalent N(3) atoms to form a mixture of corner and edge-sharing VN4 tetrahedra. In the second V site, V(2) is bonded in a 4-coordinate geometry to one N(1), one N(2), and two equivalent N(4) atoms. In the third V site, V(3) is bonded to one N(1), one N(2), one N(4), and one N(5) atom to form distorted corner-sharing VN4 tetrahedra. There are three inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a single-bond geometry to one N(2) atom. In the second Pb site, Pb(2) is bonded in a distorted single-bond geometry to one N(5) atom. In the third Pb site, Pb(3) is bonded in a 4-coordinate geometry to one N(1), one N(2), and two equivalent N(3) atoms. There are five inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to one V(1), one V(2), one V(3), and one Pb(3) atom. In the second N site, N(2) is bonded in a 2-coordinate geometry to one V(2), one V(3), one Pb(1), and one Pb(3) atom. In the third N site, N(3) is bonded in a distorted L-shaped geometry to two equivalent V(1) and two equivalent Pb(3) atoms. In the fourth N site, N(4) is bonded in a distorted T-shaped geometry to one V(3) and two equivalent V(2) atoms. In the fifth N site, N(5) is bonded in a distorted T-shaped geometry to one V(1), one V(3), and one Pb(2) atom. is represented by the CIF file [CIF]
