Abstract
Two new neutral nano flower polymeric lead(II) coordination compounds, [Pb(tmph)(μ-SCN)2]n (1) and [Pb(tmph)(μ-NO3)2]n (2), [tmph = 3,4,7,8-tetramethyl-1,10-phenanthroline], have been synthesized by a sonochemical process and characterized by scanning electron microscopy (SEM), X-ray powder diffraction (XRPD), FT-IR spectroscopy and elemental analyses. SEM image shows the nano flower morphology for the products. Single-crystal X-ray studies show that the overall structure of the both 1 and 2 are 1D double chain net-like coordination polymers. Compound 1 has a very rare bridging cyanato pathway; a tetra dentate bridging between four PbII centers. 1D double chains of compounds 1 and 2 further extended into two-dimensional (2D) and three dimensional (3D) supramolecular structures by strong π-π directional intermolecular interactions, respectively.
