摘要

An unprecedented 2D cadmium(II) coordination polymer {[Cd-3(L)(2)(mu(1,5)-dca)(6)](H2O)}(n) (1) of potentially tridentate NNN donor Schiff base ligand (L) [L = 1-(4,6-dimethylpyrimidin-2-yl)-2-(dipyridin-2ylmethylene) hydrazine] with the point symbol {4(3)}(2){4(6).6(6).8(3)} has been synthesized and characterized by elemental analyses, IR, H-1 NMR, emission spectroscopy and single crystal X-ray crystallography. The dicyanamide ions act as linker in the formation of the said,coordination polymer. Complex 1 has distorted octahedral geometry around the Cd(II) centers. Interestingly, two different ligand environments are observed around Cd(II) center. Each Cd(L) fragment is connected by three six connecting nodes of [Cd(NCN)(6)] units to form the 2D coordination polymer of 3,6 connecting binodal system. In addition, the complex molecule gains extra stability by pi-pi interaction.
