Two Discrete Cu-Complexes Constructed from a Multidentate N-Containing Dinucleating Ligand

Two comparable discrete complexes[Cu~Ⅱ(CH_3CN)_2L_2]·2(ClO_4)1 and[Cu_2~ⅠI_2L_2]·(DMF)_2 2 were successfully synthesized by the reaction of Cu~Ⅱ and Cu~Ⅰ salts with a novel dinucleating ligand 2,5-bis(3-pyridinylmethylthio)1,3,4-thiadiazole)(L),respectively.Complex 1 presents a single nuclear structure while 2 has a dimeric structure where two Cu~Ⅰ ions are doubly bridged by halide ions in a μ2-fashion.Both discrete molecules were outspreaded into a one-dimensional supramolecular chain via aromatic interctions such as C-H…π and π…π interactions.
