Abstract
The reaction of [Cu(CH3CN)4](BF4) with 1-methyl-1,3-imidazolidine-2-thione {SC3H4(NMe)NH}, under aerobic conditions at room temperature, yielded an unusual one-dimensional coordination polymer, namely, catena-poly[[[(1-methyl-1,3-imidazolidine-2-thione-κS)copper(I)]-μ-(1-methyl-1,3-imidazolidine-2-thione)-κ2 S:S-copper(I)-μ-[3,3′-(sulfanediyl)bis(1-methyl-1,3-imidazolidine-2-thione)]-κ5 S,S′,S′′:S,S′′] bis(tetrafluoridoborate)], {[Cu2(C4H8N2S)2(C8H14N4S3)](BF4)2} n or [Cu4(κ5:L 1 - N - S - N - L 1)2(κ1:L 1 - NH)2(κ2:L 1 - NH)2] n (BF4)4n 1 [L 1 = SC3 H4(NMe)NH] with sulfur-bridged {CuI 4S10} n central cores. The in situ generated bis(1-methyl-1,3-imidazolidinyl-2-thione) sulfide [{SC3H4(NMe)NSN(NMe)C3H4S; abbrev. L 1 - N - S - N - L 1] ligand, in combination with 1-methyl-1,3-imidazolidine-2-thione (L 1 - NH) ligands, construct this coordination polymer. Each CuI ion is bonded to four sulfur donor atoms in a distorted tetrahedral geometry and the formation of this polymer solely by sulfur donor atoms with {CuI 4S10} n central cores, is the first such example in copper-heterocyclic-2-thione chemistry.
