Isolation of a new two-dimensional honeycomb carbonato-bridged copper(II) complex exhibiting long-range ferromagnetic ordering

Atmospheric CO2 fixation by an aqueous solution containing Cu(ClO4)2·6H2O and 4-aminopyridine (4-apy) yields a novel example of a two-dimensional µ3-CO3 bridged copper(II) complex {[Cu(4-apy)2]3((mu)3-CO3)2(ClO4)2·½CH3OH}n1 that has been characterized by IR, UV and X-ray crystallography; preliminary magnetic measurements show that complex 1 exhibits long-range ordered ferromagnetic coupling.
