Three new lariat dilactam host molecules were prepared by the reaction of triethyleneglycol dicarboxylic acid dichloride with N, N'-disubstituted-4, 7-dioxa-1, 10-diazadecane precursors. The amide nitrogen pivot of such compounds are substituted with the benzyl, octyl and dodecyl groups. The complexing ability of these dilactams is displayed with a series of metal complexes of Na+, K+, Ca2+, Sr2+, Pb2+ and Ag+ ions. The structures determined are consistent with the data of H-1-NMR, C-13-NMR, IR spectra and elemental analyses.
