The title compounds, mu-(tri-tert-butoxysilanethiolato-kappa2S:S)-bis[(tetrahydrofuran-kappaO)lithium(I)], [Li2(C12H27O3SSi)2(C4H8O)2], (I), and catena-poly[[bis(mu-tri-tert-butoxysilanethiolato)-1:2kappa(2)S;1kappaS:2kappaS,O-dilithium(I)]-mu-dimethoxyethane-kappa2O:O'], [Li2(C12H27O3SSi)2(C4H10O2)]n, (II), were obtained by the reaction of tri-tert-butoxysilanethiol with metallic lithium. The crude product, when recrystallized from tetrahydrofuran (THF) yields (I), and when recrystallized from 1,2-dimethoxyethane (DME) gives (II). Compound (I) forms centrosymmetric dimers in the solid state with an Li2S2 central core, whereas (II) forms infinitely long chains, in which the centrosymmetric dimeric units are linked together by the bidentate DME ligand (also residing on an inversion centre), thus forming a coordination polymer. The formation of a one-dimensional structure in (II) is a consequence of replacement of a monodentate THF solvent molecule with a bidentate DME molecule.
