A fourfold interpenetrating diamond‐like three‐dimensional zinc(II) coordination polymer: synthesis, crystal structure and physical properties

Excellent fluorescence properties are exhibited by d 10 metal compounds. The novel three‐dimensional Zn II coordination framework, poly[[{μ 2 ‐bis[4‐(2‐methyl‐1 H ‐imidazol‐1‐yl)phenyl] ether‐κ 2 N 3 : N 3′ }(μ 2 ‐furan‐2,5‐dicarboxylato‐κ 2 O 2 : O 5 )zinc(II)] 1.76‐hydrate], {[Zn(C 6 H 2 O 5 )(C 20 H 18 N 4 O)]·1.76H 2 O} n , has been prepared and characterized using IR spectroscopy, elemental analysis and single‐crystal X‐ray diffraction. The crystal structure analysis revealed that the compound exhibits a novel fourfold interpenetrating diamond‐like network. This polymer also displays a strong fluorescence emission in the solid state at room temperature.
