Temperature effect-driven assembly of [CunXn]-based coordination polymers from CuX and 1,4-bis(imidazol-1-yl)butane

Three [Cu2(μ-I)2]- or [Cu4(μ3-I)4]-based coordination polymers, {[Cu2(μ-I)2(bimb)2]·iodobenzene}n, {[Cu4(μ3-I)4(bimb)2][Cu2(μ-I)2(bimb)]}n and {[Cu2Br(bimb)2]Br}n were prepared from solvothermal reactions of CuX (X = I, Br) with 1,4-bis(imidazol-1-yl)butane (bimb) at different temperatures. These compounds were characterized by elemental analysis, IR, and single crystal X-ray diffraction and their luminescent properties were investigated.
