Abstract: The solvothermal reactions of N-allyl imidazole with CuIX (X=Cl, Br) afford two unprecedented 3D copper(I)–olefin coordination polymer Cu2X2(N-allyl imidazole) (X=Cl for 1; Br for 2). This is the first 3D copper(I)–olefin coordination polymer synthesized in directed method, compared to most of olefin–Cu(I) coordination polymers prepared by electrochemical method. Of practical interest is that both of them contain 1D zigzag ladder chain composed of basic Cu2X2 dimer unit. Photoluminescent measurements show that 1 displays blue fluorescent emission while 2 has red fluorescent emission at room temperature. [Copyright &y& Elsevier]

Abstract: Under hydrothermal conditions, the reaction of 3,5-diaminobenzoic acid (HDABC) with Cd(ClO4)2∼6H2O affords a novel 2D network, {[Cd(DABC)2][Cd(DABC)2(H2O)2]}n (1), which, represents the first example of 2D neutral polymeric material containing DABC ligand with strong blue fluorescent emission in the solid state.
