N2  - The crystal structures of the title compounds have been carried out by single-crystal X-ray diffraction methods at 295 K. For (1), [(EtOCS2)Pb(C9H6NO)2Pb(S2COEt)], crystals are triclinic, P1, a 11.600(6), b 8.9739, c 6.863(4) Å, &#945; 96.79(5), &#946; 90.19(5), &#947; 101.54(4)º, with one dimer in the cell. R was 0.038 for 3109 'observed' reflections. The lead atom is coordinated by two sulfur atoms from the xanthate ligand [Pb-S 2.705(3), 3.173(3) Å], the quinolin-8-olato nitrogen atom [Pb-N 2.479(6) Å] and the oxygen atom which bridges two centrosymmetrically related lead atoms [Pb-O 2.296(5), 2.548(4) Å]. For (2), (Et4N) [Pb(S2COEt)3], crystals are monoclinic, P21/c, a 10.827(3), b 18.889(6), c 14.292(5) Å, &#946; 111.05(2)º, Z 4. R was 0.050 for 3657 'observed' reflections. The lead atom is surrounded by the six sulfur atoms [Pb-S 2.754(4)-3.126(3) Å], with close approaches from the two sulfur atoms of one of the ligands of a centrosymmetrically related anion [Pb.. .S 3.545(4), 3.555(4) Å], in a similar manner to that observed in the 'isoelectronic' tris(N,N-diethyldithiocarbamato)bismuth(III) complex.
