The preparation of the two 4-alkyl-2(1H)pyridinethione ligands mpySH and epySH is described. The coordination behaviour of these ligands with copper(I) is reported. In general the patterns of reactivity resemble those of 2(1H)pyridinethione itself. A variety of dinuclear complexes is described together with the structural characterisation of the paddle-wheel complexes [Cu6(mpyS)6] (space group P 1̄, a = 9.392(2), b = 9.642(2), c = 11.527(2) Å, α = 80.79(2), β = 87.66(2), γ = 86.31(2)°) and [Cu6(epyS)6] · 2H2O (space group P 1̄, a = 11.131(4), b = 11.929(4), c = 11.992(4) Å, α = 109.94(1), β = 106.61(1), γ = 109.33(1)°). Although the gross paddle-wheel structure is similar in each case, the variation of the substituent results in significant variation in the geometry of the hexanuclear cluster.
