Incorporation of generated 3,3'-(sulfane-diyl)bis-(1-methyl-1,3-imidazolidine-2-thione) into a one-dimensional Cu coordination polymer with sulfur-bridged {Cu S} central cores.

The reaction of Cu(CHCN) with 1-methyl-1,3-imidazolidine-2-thione {SCH(NMe)NH}, under aerobic conditions at room temperature, yielded an unusual one-dimensional coordination polymer, namely, -poly[[[(1-meth-yl-1,3-imidazolidine-2-thione-κ)copper(I)]-μ-(1-methyl-1,3-imidazolidine-2-thione)-κ :-copper(I)-μ-[3,3'-(sulfanedi-yl)bis-(1-methyl-1,3-imidazolidine-2-thione)]-κ ,','':,''] bis-(tetra-fluorido-borate)], {Cu(CHNS)(CHNS)} or [Cu(κ: -N-S-N- )(κ: -NH)(κ: -NH)] (BF) [ = SC H(NMe)NH] with sulfur-bridged {Cu S} central cores. The generated bis-(1-methyl-1,3-imidazolidinyl-2-thione) sulfide [{SCH(NMe)NSN(NMe)CHS; abbrev. -N-S-N- ] ligand, in combin-ation with 1-methyl-1,3-imidazolidine-2-thione ( -NH) ligands, construct this coordination polymer. Each Cu ion is bonded to four sulfur donor atoms in a distorted tetra-hedral geometry and the formation of this polymer solely by sulfur donor atoms with {Cu S} central cores, is the first such example in copper-heterocyclic-2-thione chemistry.
