Two novel hybrid compounds based on [MW12O40]5− (M = B, Al) heteropolyanions and copper coordination polymer with bpp ligands

Under hydrothermal condition, two novel organic-inorganic hybrid compounds, [Cu(bpp)][Cu2.5(bpp)3(Hbpp)]H0.5[BW12O40]·1.5H2O (1) and [Cu(en)2(H2O)] {[Cu(bpp)]3[AlW12O40]}·H2O (2) (bpp = 1,3-bis(4-pyridyl)propane; en = ethylenediamine), have been synthesized based on B/Al atom-centered Keggin-type polyoxometalates combined with Cu ions and bpp ligands.
