The compounds Ph3SnR [R = (CH2)2C5H5N-2 (1), (CH2)2C5H5N-4 (2), and (CH2)2C3H6C(O)N-2 (3)] have been synthesized by hydrostannylation of 2- or 4-vinylpyridine and N-vinylpyrrolidin-2-one, respectively, with Ph3SnH. Reaction of 1-3 with 1 equiv of X2 (X = Br, I) gives Ph2RSnX, which have been used to synthesize representative compounds of general formula Ph2RSn(L), L = S2CNR′2 (R′ = Me, Et) or O2CR′ (R′ = Me, Ph). The structures of the compounds are discussed on the basis of their 1H, 13C, 119Sn NMR and 119Sn M?ssbauer data The structure of Ph2Sn[(CH2)2C5H 5N-2](S2CNMe2) has been determined by X-ray crystallography: C22H24N2S2Sn, fw 499.28, a = 9.611 (4) ?, b = 10.255 (3) ?, c = 12.896 (9) ?, α = 75.35 (4)°, β = 70.97 (4)°, γ = 68.09 (3)°, V = 1102.2 ?3, Z = 2, space group P1, ρcalc = 1.50 g cm-3, μ(Mo Kα) = 12.42 cm-1, λ(Mo Kα) = 0.710 69 ?, F(000) = 504, R = 0.0492, Rw = 0.0542 for 2133 unique data. The tin is in a five-coordinate, trigonal bipyramidal trans-NSSnPh2R environment, with nitrogen and sulfur in the axial positions. The 2-ethylpyridyl ligand chelates the metal, while the dithiocarbamate is monodentate.
