A new hetero-ditopic cryptand with naphthyl side groups has been synthesized by tripod-tripod Schiff base condensation of a tripodal trialdehyde withtris(2-aminoethyl)amine in presence of Cs(I) ion. This cryptand reacts readily with Cu(II) and Ni(II) salts forming mononuclear cryptates. The Cu(II)-cryptate can accept a molecule of H2S which is tightly bound to the metal ion forming a CuN4S complex. The electronic spectral characteristics are indicative of the presence of Cu-SH2 bond.
