Triorganophosphinegold(I) complexes of the anions derived from pyridine-2-thione (2-pySH) and 1H-pyrimidine-2-thione (2-pymSH), (R = Et, Ph or C6H11), have been prepared and characterized by spectroscopic (IR, 1H and 13C NMR and fast atom bombardment MS) methods and for the PPh3 compounds by X-ray crystallographic techniques.The mononuclear compounds feature linear gold atom geometries defined by P and S atoms with important parameters for : Au-P 2.258(1), Au-S 2.297(2) Angstroem and P-Au-S 177.9(1) deg and for : Au-P 2.253(2), Au-S 2.310(3) Angstroem and P-Au-S 174.7(1) deg.The complex 2 crystallizes in the monoclinic space group P21/c with unit-cell dimensions a = 12.235(1), b = 10.009(2), c = 17.292(2) Angstroem, β = 104.08(1) deg and Z = 4; 5 crystallizes in the triclinic space group <*> with a = 11.006(2), b = 11.356(4), c = 8.873(1) Angstroem, α = 109.85(2), β = 95.72(1), γ = 93.55(2) deg and Z = 2.The structures were refined to final R = 0.025 for 2527 reflections with I > 2.5?(I) and R = 0.057 for 3416 reflections with I > 2.5?(I) for 2 and 5, respectively.
