“…The IR spectra of 3 displayed bands at 1144 and 1048 cm -1 assignable to ν as (SO 2 ) and ν s (SO 2 ), respectively, well within the expected range . The IR spectra of 4 are consistent with monodentate monothiocarbamates; , the ν(CN) and ν(CO) bands are clearly resolved and consistent with the monodentate S-bound form observed in the crystallographic determination.…”

The reactions of Ru(bpy)(2)(N,N-dimethyldithiocarbamate)(+), 1, with O-atom-transfer reagents such as hydrogen peroxide, m-chloroperoxybenzoic acid, and oxone have been studied and several resulting derivatives isolated and structurally characterized. Both S-oxygenation and S-extrusion may occur depending upon reagent and conditions. Excess peroxygenation leads to a stable dioxygenate, Ru(bpy)(2)(N,N-dimethylthiocarbamatesulfinate-S,S)(+), 3. Stoichiometric oxygenation leads to mixtures of products from which two forms of monooxygenated species Ru(bpy)(2)(N,N-dimethylperoxydithiocarbamate-S,S), 2a, and Ru(bpy)(2)(N,N-dimethylperoxydithiocarbamate-O,S), 2b, and an S-extruded product, Ru(bpy)(2)(N,N-dimethylmonothiocarbamate)(+), 4, have been isolated as PF(6)(-) salts. The S,S-bound monooxygenate is unstable over time toward either O-atom-transfer reactions via disproportionation or reaction with phosphines or S-extrusion yielding complex 4 in which the thiocarbamate is bonded solely through the remaining S atom. All the complexes have been characterized by (1)H NMR, UV-vis, and mass spectroscopies, and all but the highly reactive 2a structurally determined by X-ray crystallography.

“…These bands, which compare favorably with those reported previously for thiocarbamate complexes, are assigned as ^(C4-4-^)) and p(C4-4-4N) frequencies, respectively.4, 16,17 The alternative assignment of the band at 1565 cm"1 as an N-H deformation is not reasonable in view of the high band intensity and the fact that N-H deformation frequencies in secondary amines are weak and rarely observed. 18 Krankovits and coworkers19 have recently proposed that the presence of a band near 1570 cm"1 in thiocarbamate complexes can be taken as an indication of uncoordinated oxygen.…”

“…The infrared spectrum of Co(SOCN(C4H8))2(NC4H9)2 is consistent with that found for other thiocarbamate complexes. 16 Of particular interest is the 1500-1600-cm"1 region of the spectrum where the and C^-^N stretching frequencies have been previously assigned.4,16 A strong, relatively sharp band is located at 1565 cm"1 and another strong, somewhat broader band is centered at 1515 cm"1.…”

The crystal and molecular structure of the complex bis(cyclotetramethylenethiocarbamato)bis(pyrrolidine)cobalt(II), Co(SOCN(C4H8))2(NC4H9)2, has been examined by single-crystal X-ray structural techniques. The complex crystallizes in the orthorhombic space group Pccn (D2/j10, No. 56) with cell dimensions of a = 12.102 (3) A, b = 15.013 (3) A, c = 12.556 (3) A, and Z = 4. The intensities of 3734 reflections were measured on an automated Picker four-circle diffractometer of which 992 have been included in the refinement. Full-matrix least-squares analysis including hydrogen atoms gave final discrepancy factors of .Rj = 0.046 and R2 = 0.049. The Co(II) ion is located at a center of twofold symmetry imposing C2 symmetry on the molecule. The coordination geometry about the metal resembles a distorted octahedron with the thiocarbamate ligands chelated to the metal (Co-S = 2.584 (2), Co-0 = 2.157 (4) A) and the pyrrolidine ligands bonded in cis positions (Co-N(l) = 2.134 (5) A). Solid-state spectral and magnetic properties of the complex are typical of distorted octahedral Co(II) systems and are consistent with the results of the molecular structure determination.

“…A strong, broad band in the spectrum of the complex at 1500 cm" 1 is assigned to v[C^O) + f(CnN) [23], which places this mode outside the range found in S-monodentate complexes [3]. The assignation of v(CaS) to a band at 940 cm 1 is in keeping with the structural results.…”

DimethyKdiethylmonothiocarbamato)thallium(IM), [TIMe 2 {S(0)CNEt 2 }] was synthesized by reacting TIMe 2 (N0 3 ) and [Et 2 NH 2 ][S(0)CNEt 2 ] in ethanol. The compound crystallized in the monoclinic space group P2,/n (No. 14) with a= 7.3379(4), b= 8.030(1), c= 19.032(3) Ä and β= 100.611(8)°, V= 1102.2(2) Ä 3 and Z= 4. The structure consists of [TIMe 2 {S(0)CNEt 2 }] units in which the thallium atom is coordinated to the two methyl carbons and to the S and 0 atoms of the bidentate monothiocarbamato (Tl-S = 2.766(3), TI-0 = 2.684(7) Ä). These units are connected by additional TI-0 bonds (Tl-O" = 2.690(7) Ä) and weak Tl-S interactions (Tl-S 1 = 3.315(3) Ä), giving rise to a supramolecular polymeric ribbon along the b axis with practically symmetrical TI-O-TI bridges. The IR and 1 H and 13 C NMR spectra of the compound are also discussed. / •N \ V C =N \ / .C-N \ (i) (in) Scheme I 231 Brought to you by |
