Abstract: Copper(n) complexes of a tridentate nitrogen donor ligand, 2,6-bis(3,5-dimethylpyrazol-l-ylmethyl)pyridine (L), CuLX2 (X = Cl, Br, NO3, NCS or ClO4) have been synthesized and characterized using UV-Vis and EPR spectra and electrochemistry. The EPR spectra reveal significant variations in a polycrystalline medium. Copper in all the compounds exhibits a stereochemistry close to a square based pyramid with trigonal bipyramidal distortion and the distortion is more pronounced in CuL(NO3)2. CuLCl2 and CuLBr2 crystallize in space group Cllc and the molecules are arranged in the lattice such that they form columnar packing along the crystallographic a axis. CuL(NOi)2 crystallizes with space group P2Jc and forms discrete dimeric units through inter- and intra-molecular hydrogen bonding involving the nitro group and methyl and méthylène groups. The polycrystalline EPR spectrum is characteristic of a triplet state. The electrochemical properties of these compounds are also discussed. © The Royal Society of Chemistry 2000.
