Novel magnesium pyridine-2-thiolates were prepared by using alkane elimination chemistry. The resulting complexes display a metal coordination environment composed of sulfur/nitrogen bonding from the intramolecularly stabilized mercaptopyridine ligand, in addition to coordination by the oxygen centers from two THF donors. The compounds are well-suited model compounds for the magnesium centers in Photosystem
thiol in methanol yields [Co(2-SC5H3N-3-SiMe3)3]. The crystalstructure determination revealed the meridional ligand arrangement, as previously reported for the analogous [Co(2-SC5H4N]. Crystal data: C24H36N3Si3S3Co, monoclinic space group P21/c, a = 9.416(2), b = 29.163(4), c = 12.371(2) A. β = 106.81(1)°, Z = 4, Dcalc = 1.23 g cm−3; structure solution and refinement based on 1032 reflections with

Abstract A series of complexes of Ni, Cu, Zn and Cd with 3-trimethylsilylpyridine-2-thione (3-Me 3 SipytH) as ligand has been prepared. Complexes [M(3-Me 3 Sipyt) 2 ] (M=Ni(II), Zn(II) and Cd(II)) and [Cu(3-Me 3 Sipyt)] are obtained by electrochemical oxidation of the metal in an acetonitrile solution of the neutral ligand (3-Me 3 SipytH). Adducts [Ni(3-Me 3 Sipyt) 2 L] (L=2,2-bipyridine or 1,10-phenanthroline)

Abstract The reaction of [Cr(CO) 6 ] with a series of heterocyclic bidentate (N,S) ligands in refluxing mesitylene afforded the homoleptic trischelate complexes [Cr(3-Me 3 SipyS) 3 ] ( 2 ), [Cr(3-CF 3 pyS) 3 ] ( 3 ) and [Cr(5-CF 3 pyS) 3 ] ( 4 ), where R-pyS stands for the anion of the corresponding substituted pyridine-2-thione ligand. Studies in the solid state by X-ray diffraction showed that the

The hydridecomplex [ReH5(PMe2Ph)3] reacted with 2-mercaptopyridine (pySH) in the presence of HBF4 giving [ReH(pyS)(PMe2Ph)4]BF4 (1) and [ReHF(pyS)2 (PMe2Ph)2]BF4 (2). The X-raystructures of both complexes have been determined and are discussed. The known complex [ReH(pyS)2(PPh3)2] and new [ReH(SipyS)2(PPh32] (3) have been prepared directly from [ReOCl3(PPh3)2], NaBH4 and the appropriate thiol. Analogous
