Construction of a new 3D Zn(II) coordination polymer with (4,6)-connected topology: Synthesis, structure and luminescence

A new coordination polymer of {[Zn2(odpa)(IP)]·4H2O}n (1) (H4odpa = 3,3′,4,4′-oxydiphthalic acid and IP = 1-H-imidazo[4,5-f][1,10]-phenanthroline), is reported. The 3D (4,6)-connected {44∙62∙88∙12}{44∙62} topology net is formed by IP and odpa ligands in 1. Interestingly, the IP ligand acts as a tridentate mode and extends the resulting 3D feature. The luminescence study indicates that the title compound emits bright red fluorescence.
