Os2Pb3N4 crystallizes in the orthorhombic Pnna space group. There are two inequivalent Os sites. In the first Os site, Os(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing OsN4 trigonal pyramids. In the second Os site, Os(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing OsN4 trigonal pyramids. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a water-like geometry to two equivalent N(2) atoms. In the second Pb site, Pb(2) is bonded in a distorted bent 150 degrees geometry to two equivalent N(1) atoms. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to one Os(1), one Os(2), and one Pb(2) atom. In the second N site, N(2) is bonded to one Os(1), one Os(2), and two equivalent Pb(1) atoms to form corner-sharing NOs2Pb2 tetrahedra.

In the first Os site, Os(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing OsN4 trigonal pyramids. Both Os(1)-N(1) bond lengths are 1.90 Å. Both Os(1)-N(2) bond lengths are 2.04 Å. In the second Os site, Os(2) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form distorted edge-sharing OsN4 trigonal pyramids. Both Os(2)-N(1) bond lengths are 1.96 Å. Both Os(2)-N(2) bond lengths are 1.97 Å. There are two inequivalent Pb sites. In the first Pb site, Pb(1) is bonded in a water-like geometry to two equivalent N(2) atoms. There is one shorter (2.42 Å) and one longer (2.48 Å) Pb(1)-N(2) bond length. In the second Pb site, Pb(2) is bonded in a distorted bent 150 degrees geometry to two equivalent N(1) atoms. Both Pb(2)-N(1) bond lengths are 2.57 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a 3-coordinate geometry to one Os(1), one Os(2), and one Pb(2) atom. In the second N site, N(2) is bonded to one Os(1), one Os(2), and two equivalent Pb(1) atoms to form corner-sharing NOs2Pb2 tetrahedra.
