Bis([mu]-2-methylquinolin-8-olato)-[kappa]3N,O:O;[kappa]3O:N,O-bis[(acetato-[kappa]2O,O')lead(II)]

Abstract top

Both independent PbII atoms in the title compound, [Pb2(C10H8NO)2(C2H3O2)2], are chelated by acetate and substituted quinolin-8-olate anions; the O atoms of the quinolin-8-olates also bridge to confer a five-coordinate status to each metal center. The geometry approximates a distorted [Psi]-fac octahedron in which one of the sites is occupied by a stereochemically active lone pair.

Related literature top

The structural chemistry of lead(II) 8-hydroxyquinolinates has been reviewed; for bis(µ-acetato)diacetatotetrakis(µ-quinolin-8-olato)tetralead dihydrate in particular, see: Shahverdizadeh et al. (2008).

Experimental top

Lead acetate (0.38 g, 1 mmol) and 2-methyl-8-hydroxyquinoline (0.32 g, 2 mmol) were loaded into a convection tube; the tube was filled with dry methanol and kept at 333 K. Crystals were collected from the side arm after 1 day.

Refinement top

Carbon-bound H-atoms were placed in calculated positions (C—H 0.93 to 0.98 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2 to 1.5U(C).

The quinolinyl ring was refined as a rigid group with C-C = 1.39 Å. The crystal diffracted strongly owing to two extremely heavy metal atoms. However, their presence introduced severe absorption problems that could not be corrected analytically as the crystal did not have regular faces. Although a sphere of reflections was measured, multi-scan treatment only marginally improved the quality. The final difference Fourier map had large peaks/deep holes near the lead atoms. The anisotropic displacement factors of the carbon, nitrogen and oxygen atoms had to be restrained to be nearly isotropic.
