The material described by PbGeN2 crystallizes in the orthorhombic Cmce space group. Pb(1) is bonded in a distorted trigonal non-coplanar geometry to one N(1) and two equivalent N(2) atoms. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form a mixture of corner and edge-sharing GeN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded in a 4-coordinate geometry to two equivalent Pb(1) and two equivalent Ge(1) atoms. In the second N site, N(1) is bonded in a 3-coordinate geometry to one Pb(1) and two equivalent Ge(1) atoms. is represented by the CIF file [CIF]
