A novel coordination polymer constructed from 1D neutral chains via inter-chain π-π stacking and hydrogen bonding

A novel 1D neutral coordination polymer, {[Cu(dtmp)(dmf)Cl-2]dmf}(n) (1) (dtmp = 1,6-di(triazole-1-yl-methyl)-4-methylphenol, dmf = dimethyl formamide) was synthesized by reacting CuCl2 (.) 2H(2)O with the dtmp ligand. The crystal and molecular structure of the complex was determined by X-ray diffraction, in which the coordination geometry around the copper center is slightly distorted trigonal bypyramidal. One-dimensional chains have been formed through the metal and the ligand via coordination bonds, which are assembled further into a two-dimensional network by inter-chain synergic pi-pi stacking and hydrogen bonding.
