Two new olefin-Cu(I) coordination polymers based on 2,5-dimethyl piperazine: synthesis, crystal structure and photoluminescent property

Two novel Olefin-copper(I) coordination polymers, whose are named [Cu3(DADMP)Cl4]n (1) and [Cu2(DADMP)Br2]n (2) (DADMP = 1,4-Diallyl-2,5-Dimethyl-piperazine), were synthesized through the solvothermal reactions of CuCl, CuBr and 2,5-dimethyl-piperazine and further characterized by powder and single crystal X-ray diffraction, as well as elemental analysis and TGA. The title polymers crystallized in the monoclinic P21/C space, both featuring two-dimensional network structure. Their fluorescent properties were also investigated.
