The structure described by Ga3Pb3N5 crystallizes in the triclinic P-1 space group. There are three inequivalent Ga sites. In the first Ga site, Ga(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 GaN4 tetrahedra. In the second Ga site, Ga(2) is bonded to one N(1), one N(2), and two equivalent N(4) atoms to form a mixture of distorted corner and edge-sharing GaN4 trigonal pyramids. In the third Ga site, Ga(3) is bonded to one N(1), one N(2), one N(4), and one N(5) atom to form a mixture of corner and edge-sharing GaN4 tetrahedra. There are three inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a water-like geometry to one N(2) and one N(3) atom. In the second Pb site, Pb(2) is bonded in a 3-coordinate geometry to one N(3) and two equivalent N(5) atoms. In the third Pb site, Pb(3) is bonded in a 3-coordinate geometry to one N(1), one N(2), and one N(4) atom. There are five inequivalent N sites. In the first N site, N(1) is bonded to one Ga(1), one Ga(2), one Ga(3), and one Pb(3) atom to form distorted NGa3Pb trigonal pyramids that share  a cornercorner with one N(2)Ga2Pb2 trigonal pyramid, corners with two equivalent N(5)Ga2Pb2 trigonal pyramids, corners with two equivalent N(4)Ga3Pb trigonal pyramids,  an edgeedge with one N(2)Ga2Pb2 trigonal pyramid, and  an edgeedge with one N(4)Ga3Pb trigonal pyramid. In the second N site, N(2) is bonded to one Ga(2), one Ga(3), one Pb(1), and one Pb(3) atom to form distorted NGa2Pb2 trigonal pyramids that share  a cornercorner with one N(5)Ga2Pb2 trigonal pyramid,  a cornercorner with one N(1)Ga3Pb trigonal pyramid, corners with two equivalent N(4)Ga3Pb trigonal pyramids,  an edgeedge with one N(1)Ga3Pb trigonal pyramid, and  an edgeedge with one N(4)Ga3Pb trigonal pyramid. In the third N site, N(3) is bonded in a distorted see-saw-like geometry to two equivalent Ga(1), one Pb(1), and one Pb(2) atom. In the fourth N site, N(4) is bonded to one Ga(3), two equivalent Ga(2), and one Pb(3) atom to form distorted NGa3Pb trigonal pyramids that share  a cornercorner with one N(5)Ga2Pb2 trigonal pyramid, corners with two equivalent N(2)Ga2Pb2 trigonal pyramids, corners with two equivalent N(1)Ga3Pb trigonal pyramids,  an edgeedge with one N(2)Ga2Pb2 trigonal pyramid,  an edgeedge with one N(1)Ga3Pb trigonal pyramid, and  an edgeedge with one N(4)Ga3Pb trigonal pyramid. In the fifth N site, N(5) is bonded to one Ga(1), one Ga(3), and two equivalent Pb(2) atoms to form distorted NGa2Pb2 trigonal pyramids that share  a cornercorner with one N(2)Ga2Pb2 trigonal pyramid,  a cornercorner with one N(4)Ga3Pb trigonal pyramid, corners with two equivalent N(1)Ga3Pb trigonal pyramids, and  an edgeedge with one N(5)Ga2Pb2 trigonal pyramid. is represented by the CIF file [CIF]
