چکیده
The title compound, [Li(2)(C(5)H(4)NOS)(2)(C(2)H(6)O)](n), having two formula units in the asymmetric unit, forms infinite chains of Li(2)O(2) rhombi along b, consisting of four independent Li and O atoms. Metal binding to 2-thio-oxo-1,2-dihydro-pyridin-1-olate occurs in a bidentate fashion via O and S, and in a monodentate manner via the N-oxide O atom. π-π Inter-actions between polymeric chains are evident from centroid-to-centroid distances of pyridine-thione fragments of 3.461 (6)-3.607 (6) Å. The N-O and C-S bond lengths are distinctively different from those in hitherto investigated Ni(II), Zn(II) and (H(3)C)(2)Tl(III) complexes of 2-thio-oxo-1,2-dihydro-pyridin-1-olate, but correlate with those reported for 1-hydr-oxy- and 1-alkoxy-pyridine-2(1H)-thio-nes in the solid state.

The basic structural unit of the title polymeric ribbon, {[Li2(C5H3N2O2)2(H2O)2]·H2O} n , is a centrosymmetric dinuclear complex in which the two Li(I) ions are bridged by two carboxyl-ato O atoms, to generate a centrosymmetric Li2O2 core. These are connected into a chain along [01-1] by carboxylic acid-carbonyl-O bonds. The tetra-hedral coordination of the Li(I) cation is completed by an aqua ...
