Abstract

{The metal-chelating ability of 2-pyrrolylthiones is described. The readily available ligands di-2-pyrrolyl thione (6), 2-thioncetylpyrrole (10), and 2-thiobenzoylpyrrole (11) constitute examples of monoanionic ligands with N,S-donor atom sets, although di-2-pyrrolyl thione (6) could theoretically also achieve chelation through an N,N-donor set. A square planar Ni(II)) complex, 14, an octahedral Co(III) complex, 18, and a tetrahedral Hg(II) complex, 17, with the di-2-pyrrolyl thionato chelate have been prepared, and their structures have been characterized by H-1 NMR, UV-vis, MS, IR, elemental analysis, and single-crystal X-ray difraction. Crystal data for 14: C18H14N4N4-NiS2.0.28H(2)O, NiS2.0.28H(2)O, trigonal, R (3) over bar, a 18.467(1) Angstrom
