Pyridine thiolato

The compound [Pt(terpy)(SCH2CH20H)]N03 is a dark red-purple microcrystalline material that is extremely water soluble. The complex is stable in cold aqueous solution for periods up to several weeks. High pH or heating (T >60°) leads to decomposition, however. The electronic absorption spectra of the ter-pyridine thiolato compounds are characteristically definitive in the 300-350 nm region and may be used to determine product purity. Solutions of [Pt(terpy)-(SCH2 CH2 OH)] N03 of less than 15 pM obey Beer s law and exhibit the following absorption maxima and molar extinction coefficients 475 (890), 342 (12,900), 327 (10,700), 311 (10,300), 277 (20,300), and 242 (28,700) nm. 

Complex (77) has been obtained by electrolysis of the respective Ni11 species (i 1/2= —0.78 V vs. Cp2Fe/Cp2Fe+ in DMF) and represents the first Ni111 complex with aliphatic thiolato donors that could be characterized crystallographically.300 The overall square planar structure is retained, but the Ni—N and Ni—S distances shorten by 0.023 A and 0.057 A, respectively, upon oxidation. While (77) is EPR-silent, its pyridine adduct shows an axial spectrum (g = 2.313, 2.281, 2.000) with N-hyperfine coupling of the z-component, indicative of a (r )1 ground state.

Pyridine-2-olate and pyridine-2-thiolate (L ) complexes [Ru(bpy)2L]+ have been prepared and characterized. Both complexes are room-temperature emitters the excited state lifetimes are 100 ns and 90 ns for the pyridine-2-thiolato and pyridine-2-olato complexes, respectively. The electrochemical properties of both complexes have been described." ...

Using tridentate ligands with various functionalities and coordinating abilities, a series of neutral and cationic tri-, tetra- and hexanuclear metalla-cycles have been synthesised [34]. Cyclic tetramers composed of Cp Ir, Cp Rh or (arene)Ru half-sandwich complexes and 6-purinethione derivatives have been isolated as triflate salts [351. The cationic complex (Cp Ir)4(Ll)4 (where L1 = 2-amino-6-purinethione), presented in Fig. 9a, forms in the solid state an infinite channel-like structure with, S symmetry. Replacing the 6-purinethione with pyridine-4-thiolato bridging ligands (L2), the trinuclear metalla-cycle [(Cp Ir)3(L2)3] was obtained (Fig. 9b) [36].

Cw-dioxomolybdenum(Vl) complexes of sterically bulky (thiolato)pyridine (41) and bi(thiolato)pyridine (42) ligands were designed to prevent comproportionation and maintain mononuclearity during oxygen-atom transfer reactions. The complex with (41) had a distorted octahedral structure and achieved its designed objective, whereas that with (42) did not, having trigonal bipyramidal structure with axial thiolate donors. 

Examples of the successful application of this method are the use of cop-per(II) acetate for the preparation of neutral complexes [Cu(SR)] (R = aryl, alkyl no base needed) (46), and the use of copper(II) nitrate for the synthesis of anionic species [Cu4(SPh))6]2 and [Cu5(SPh)7]2- (47, 48), as well as of the cationic species [Cu,(SC5H4NH)3]+ (49). The latter complex is interesting in that each thiolate ligand is neutral due to protonation of the pyridine nitrogen atom. Similarly, silver nitrate has been used to prepare several neutral alkyl-thiolato silver complexes (33). The use of copper(I) oxide was reported in the synthesis of a family of copper(I) arenethiolates containing intramolecularly... 

In the complex Cp Rhm(PyS)2 (PyS = pyridine-2-thiolato), one PyS ligand is bound to the rhodium ion in an A-monodentate mode, while the other ligand chelates to the metal in an TVA -bidentate mode. In this complex, the thiol thione tautomerism occurs in solution at ambient temperature, so its NMR spectra are solvent-dependent (00ICA(299) 100). 

Pyridine-2-thiol (LH) reacts with [Ru3(CO)l2J to yield minor amounts of [RuL2(CO)2] and predominantly [Ru3(p-H)(p3-L)(CO)9], 154, where the pyridine-2-thiolato-unit bridges two ruthenium atoms (92IC4792). 

It is well established that whereas halogen-bridged dimeric complexes of Pd are readily cleaved by unidentate ligands such as pyridine or PPh3, the corresponding thiolato-bridged complexes are not. Furthermore, only the cis isomers of the Pd thiolato-bridged...
