Spontaneous resolution of a chiral polyoxometalate: Synthesis, crystal structures and properties

Two enantiomerically pure chiral POM-based compounds, [(CH3)2NH2]10[Zr(PW11O39)2] · 10H2O (L-1 and R-1) have been prepared by conventional aqueous solution method without a chiral auxiliary. L-1 and R-1 are enantiomers and have the helical structures. The circular dichroism spectra confirmed the enantiomeric nature of them. The electrochemical property of 1 was also researched.
