PbC8H4(N2O)2 crystallizes in the orthorhombic C222_1 space group. Pb(1) is bonded in a distorted hexagonal planar geometry to two equivalent N(2) and four equivalent O(1) atoms. Both Pb(1)-N(2) bond lengths are 2.58 Å. There are two shorter (2.50 Å) and two longer (2.60 Å) Pb(1)-O(1) bond lengths. There are six inequivalent C sites. In the first C site, C(5) is bonded in a trigonal planar geometry to one C(6) and two equivalent C(4) atoms. The C(5)-C(6) bond length is 1.46 Å. Both C(5)-C(4) bond lengths are 1.41 Å. In the second C site, C(6) is bonded in a distorted trigonal planar geometry to one C(5) and two equivalent N(2) atoms. Both C(6)-N(2) bond lengths are 1.35 Å. In the third C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2) and two equivalent O(1) atoms. The C(1)-C(2) bond length is 1.48 Å. Both C(1)-O(1) bond lengths are 1.28 Å. In the fourth C site, C(2) is bonded in a trigonal planar geometry to one C(1) and two equivalent C(3) atoms. Both C(2)-C(3) bond lengths are 1.40 Å. In the fifth C site, C(3) is bonded in a distorted trigonal planar geometry to one C(2), one C(4), and one H(1) atom. The C(3)-C(4) bond length is 1.39 Å. The C(3)-H(1) bond length is 1.09 Å.
