Bis(μ-N-nitroso-N-phenyl-hydroxy-laminato)-κO,O':O';κO':O,O'-bis-[(N-nitroso-N-phenyl-hydroxy-laminato-κO,O')lead(II)]

Abstract

The four cupferronate ions in the 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 geometry of both five-coordinate Pb(II)atoms is distorted Ψ-octa-hedral; if another two longer inter-molecular Pb⋯O inter-actions [at 2.955 (1) and 3.099 (1) Å] are considered, the geometry is a distorted Ψ-square anti-prism.
