The material structure described by PbSiN2 crystallizes in the orthorhombic Pna2_1 space group. Pb(1) is bonded in a 3-coordinate geometry to one N(2) and two equivalent N(1) atoms. Si(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form corner-sharing SiN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 4-coordinate geometry to two equivalent Pb(1) and two equivalent Si(1) atoms. In the second N site, N(2) is bonded in a distorted bent 150 degrees geometry to one Pb(1) and two equivalent Si(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
