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

The reaction of Cu(ClO4)2·6H2O and 1,2-bis(4-pyridyl)ethane (bpe) in basic aqueous solution yields a 3D compound, {[Cu3(CO3)2(bpe)3]·2ClO4}n (1) through the atmospheric fixation of CO2 composing Cu(CO3) kagomé layers pillared by the bpe linker that exhibit weak antiferromagnetic interaction in the kagomé layer and interlayer ferromagnetic coupling at low temperature.
