| Abstract |
The new water-soluble 2D Cu/Na coordination polymer [Cu(mu-dipic)(2)\Na-2(mu-H2O)(4)\](n)center dot 2nH(2)O (1) has been synthesized by self-assembly in aqueous medium from copper(II) nitrate, dipicolinic acid (H(2)dipic) and sodium hydroxide in the presence of triethanolamine. It has been characterized by IR spectroscopy, FAB(+)-MS, elemental and single-crystal X-ray diffraction analyses, the latter featuring a layered 2D metal-organic structure that is extended to a 3D supramolecular assembly by extensive hydrogen bonding between adjacent layers and involving crystallization water molecules. Compound 1 has been shown to act as a catalyst precursor for the peroxidative oxidation of cyclohexane and cyclopentane to the corresponding cyclic ketones and alcohols by aqueous H2O2 in MeCN solution and in the absence of acid additives.
