A second triclinic polymorph of bis-(μ-N-nitroso-N-phenyl-hydroxy-laminato)-κ(3)O,O':O';κ(3)O':O,O'-bis-[(N-nitroso-N-phenyl-hydroxy-laminato-κ(2)O,O')lead(II)].

The cupferronate ions in the centrosymmetric dinuclear title compound, [Pb(2)(C(6)H(5)N(2)O(2))(4)], O,O'-chelate to the two Pb(II) atoms; two of the four nitroso O atoms are also involved in bridging. The geometries of the five-coordinate Pb(II) atoms in the two independent mol-ecules are Ψ-octa-hedral; if more remote Pb⋯O inter-actions are also considered, the coordination number is increased to six for one mol-ecule and to seven for the other. Their coordination polyhedra are ill defined in the chain motif, which runs along [100].
