Achieving Different Morphologies for a Zinc(II) Coordination Polymer by Green Sonochemical Synthesis and New Precursors for the Preparation of Zinc(II) oxide

A new 2D zinc(II) coordination polymer(CP) 1, [Zn(N3)(L)]n(1), [L= 2-picolinate] has been synthesized using branch tube approach. Nano and micro structures of CP 1 were synthesized using sonochemical technique in diverse conditions (different times and solvents) and they were identified by elemental analysis, FT-IR spectra, scanning electron microscopy (SEM) and powder X-ray diffraction (PXRD). Single-crystal X-ray studies show that CP1 contains Zn(II) atoms with different coordination geometries (tetrahedral and octahedral). The effects of solvents and reaction time on the morphology and size of the nano and microstructure of CP 1 were also evaluated. The results showed that change in reaction time has almost no effect on the size of particles, but change in solvent leads to changes in the morphology of particles.
