Comment

The cupferronate ion is a common ion used for the complexation of metals; the lead(II) derivative exists as a dinuclear compound, the four cupferronate ions in dinuclear [Pb(C₆H₅N₂O₂)₂]₂O,O'-chelate to the lead(II) atom, and two of the four nitroso O atoms are also involved in bridging. The geometry of both five-coordinate lead atoms is Ψ-octahedral; if another longer intermolecular Pb···O interactions (approx. 3.0 Å) are considered, the geometry is a Ψ-square-antiprism (Najafi et al., 2011). The 1,10-phenanthroline adduct is monomeric (Scheme I, Fig. 1). The two cupferronate ions and the N-heterocycle in mononuclear Pb(C₁₂H₈N₂)(C₆H₅N₂O₂)₂ chelate to the lead(II) atom; the geometry of the lead atom is a Ψ-pentagonal bipyramid.

Experimental

Lead(II) nitrate (0.33 g, 1 mmol) dissolved in ethanol (20 ml) was added to the cupferron ligand (0.31 g, 2 mmol) and 1,10-phenanthroline hydrate (0.40, 2 mmol) dissolved in ethanol (20 ml). The mixture was stirred and then set aside for the growth of brown colored crystals.

Refinement

Hydrogen atoms were placed in calculated positions (C–H 0.95 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2U_eq(C).

Omitted from the refinement were the following reflections owing to bad disagreement between the observed and calculated F² values: (0 0 1), (0 1 2), (1 0 1), (0 0 2), (11 4 7), (-9 - 11 5), (11 3 8), (11 5 6), (-4 - 9 10), (-9 - 9 2) and (3 - 2 14).
