Formation of novel Olefin-Copper(I) coordination compound dependent on conformation of Olefin ligand

► Solvothermal synthesis of olefin-copper(I) coordination compound. ► The conformation of organic ligand affects the formation of olefin-copper(I) coordination compound. ► Novel copper-halide cluster as node to construct 2D (4,4) net coordination polymer. ► High dielectric constant. ► Fluorescent influence.
