catena-Poly[(μ(3)-2-hy-droxy-4-isopropyl-cyclo-hepta-2,4,6-trien-1-onato)(μ(2)-2-hy-droxy-4-isopropyl-cyclo-hepta-2,4,6-trien-1-onato)lead(II)].

In the title compound, [Pb(C(10)H(11)O(2))(2)](n) or [Pb(hino)(2)](n), the lead(II) ion is chelated by two hinokitiolate ligands in a distorted square-pyramidal configuration, with Pb-O bond lengths in the range 2.327 (6)-2.479 (9) Å. The 6s(2) lone electron pair of the lead(II) ion becomes stereochemically active and is directed towards the apex of this pyramid. The crystal structure of the title compound consists of chains formed by the bis-(hinokitiolato)lead(II) mol-ecules situated along the twofold screw axis. The coordination sphere around the lead(II) ion is completed by three additional O atoms, at 2.625 (7), 3.016 (8) and 3.064 (8) Å, from the two neighbouring Pb(hino)(2) units. Both isopropyl groups are rotationally disordered.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
