N2 - Three novel complexes with helical two dimensional (2D) frameworks, [Ni(Asn)2(H2O)] (1) (HAsn = l-asparagine), [Cd(Gln)2]n (2) (HGln = l-glutamine) and [Zn(Gln)2]n (3), have been studied based on X-ray single crystal diffraction analysis. l-asparagine induces two kinds of chirality, the chiral Ni(II) center and the supramolecular M-helixes, into complex 1. l-glutamine induces one kind of chirality, the helixes, into complexes 2 and 3, respectively. Combining the crystal structures of complexes 1-3, the final aggregate chirality induced by coordinated bond interactions can be detected by the liquid state circular dichroism (CD) spectra while the solid state CD spectra of complexes 1-3 additionally reflect the final aggregate chirality induced by weak interactions.
