Hydrothermal synthesis of brucite type copper hydroxide squarate [Cu-3(OH)(2)(C4O4)]center dot 4H(2)O

Herein we report synthesis of a new brucite type copper hydroxide squarate, Cu-3(OH)(2)(C4O4)(2)center dot 4H(2)O [P2(1)/c, a = 5.6437(4) angstrom, b = 12.8357(9) angstrom, c = 9.1507(6) angstrom, beta = 95.892(1)degrees and Z = 2] by hydrothermal method, and its characterization by single crystal diffraction analysis as well as by IR spectroscopy. The rather wide spread of Cu-O bond lengths, can be primarily rationalised by the Jahn-Teller effect, and secondarily by the connectivities of the CuO6 octahedra.
