摘　　要：Five novel chiral dinuclear Salen complexes M2L (M = Fe3+Cl-, Mn3+Cl-, Co2+, Ni2+, Cu2+) and Ba2+-crown ether complex H4BaL(ClO4)2 were synthesized. The complexes were synthesized by reaction between ligand 3 (H4L) and corresponding metal salts (FeCl3, Mn(OAc)2·4H2O, Co(OAc)2·4H2O, Ni(OAc)2·4H2O, Cu(OAc)2·H2O, Ba(ClO4)2·2H2O). The chiral two discrete Salen ligand 3 was condensed from 3,3′-[Oxybis(2,l-ethanediyloxy)]bis(2-hydroxybenzaldehyde) and (R,R)-1,2-diamino-cyclohexane. The structure of complexes is two discrete Salen unit bridged with crown ether from two sides. We found that ligand 3 had three complex cites. The two N2O2 cavities can found complexes with d-metals (compound 4), while the O10 cavity can found complex with alkali metals and alkaline-earth metals (compound 5). The compounds were characterized by elemental analyses, 1H NMR, Mass-spectra, FT-IR, UV-Vis and CD spectra. The FT-IR, UV-Vis and CD spectra property of complexes were minutely analyzed.Five novel chiral dinuclear Salen complexes M2L (M = Fe3+Cl-, Mn3+Cl-, Co2+, Ni2+, Cu2+) and Ba2+-crown ether complex H4BaL(ClO4)2 were synthesized.
