Abstract

A chiral [M3L3]6+-type nanobowl reported here was self-assembled from cis-protected mono-palladium complex [(RRdiph)Pd](NO3)2 (where RRdiph= (1R,2R)-(+)-1,2-diphenylethylenediamine) as chiral corners and 4,7-phenanthroline ligand (L) as linkers in aqueous media. The hydrophobic cavity-containing metallo-macrocycle [Pd3L3]6+·6NO3 (1) with a syn, syn, syn orientation has been characterized by 1H NMR spectroscopy, elemental analysis, CD spectra and X-ray diffraction determination.
