Two novel olefin-copper(I) coordination polymers with DHDAB as building blocks

• Stable olefin-copper(I) coordination polymers are of interesting physical properties.
• Hydrothermal synthesis of DHDAB and CuCl offered two olefin-copper(I) compounds.
• Dielectric constants were measured at different frequencies with temperature variation.

As stable organometallic moieties, olefin-copper(I) coordination polymers are of interesting properties. In this study, bioactive benzo[d]imidazol derivative 2,2′-(1,2-dihydroxyethane-1,2-diyl) bis(1,3-diallyl-3H-benzo[d]imidazol-1-ium) bromide (DHDAB) and CuCl reacted at different temperatures under hydrothermal reaction condition to afford two olefin-Cu(I) coordination polymers with novel structural features, a 3D [(DHDAB)Cu6Br4Cl4]n frame network and a 1D [(DHDAB)Cu2Cl4]n infinite chain, respectively. The dielectric constants were measured at different frequencies with temperature variation.
