Hydrothermal syntheses and crystal structures of two CuI coordination polymers: [CuI(TATP)(CN)] n and [CuI(bpy)(SCN)] n (TATP = 1,4,8,9-tetranitrogen-trisphene, bpy = 2,2′-bipyridine)

Two new Cu^I coordination polymers, [Cu^I(TATP) (CN)] _n (1) and [Cu^I(bpy)(SCN)] _n (2) (TATP = 1,4,8,9-tetranitrogen-trisphene, bpy = 2,2′-bipyiridine), have been synthesized under hydrothermal conditions and structurally characterized by elemental analysis, IR, and X-ray crystallography. In 1 and 2, the metal centers are linked by bridging CN⁻/SCN⁻ to form one-dimensional chains in the crystals and are stabilized by interchain π–π stacking interaction.
