摘要

A cyano-bridged copper(II)-copperd) mixed valence polymer, namely {[Cu4CN)5(C5H5N)44}_n, (1), was synthesized and characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis, differential scanning calorimetric analysis, and single crystal X-ray crystallography. Single crystal X-ray studies show that the coordination polymer 1 is linked by the cyanide anions with μ-1κN:2κC bridging modes to the copper centers, generating a two-dimensional (2D) layered network. The coordination polymer 1, upon pyrolyzing, yielded copper oxide nanoparticles, which have been characterized by TEM and powder X-ray diffraction. The catalytic properties of the resulting copper oxide nanoparticles have also been studied in C-N, C-O, and C-S cross-coupling reactions with aryl halides. The C-N, C-O and C-S coupling products were obtained in moderate to good yields (66-90%, 72-98%, and 50-86%), respectively.
