A planar Cu2+ (S=1/2) kagome network pillared by 1,2-bis(4-pyridyl) ethane with interesting magnetic properties

The reaction of Cu(ClO4)(2)center dot 6H(2)O and 1,2-bis(4-pyridyl)ethane (bpe) in basic aqueous solution yields a 3D compound, {[Cu-3(CO3)(2)(bpe)(3)]center dot 2ClO(4)}(n) (1) through the atmospheric fixation of CO2 composing Cu(CO3) kagome layers pillared by the bpe linker that exhibit weak antiferromagnetic interaction in the kagome layer and interlayer ferromagnetic coupling at low temperature.
