Synthesis of a Robson type macrocyclic ligand [H4L](ClO4)2 (1) obtained on condensation of 2,6-diformyl-4-methylphenol and 2,2′-dimethyl-1,3-diaminopropane, template synthesis of a dinuclear lead(II) complex [PbII2L(NO3)2] (2), synthesis of a dinuclear zinc(II) complex [ZnII2L(NO3)(H2O)](ClO4) (3) through metal substitution reaction and synthesis of another dinuclear zinc(II) complex [ZnII2L(H2O)2](ClO4)2·(H2O)2 (4) obtained directly from 1 are described in the present study. Crystal structure determinations of 1 and 3 have been carried out. Both the compounds 1 and 3 crystallize in the orthorhombic system with the space groups Fdd2 and P21212, respectively. Spectrophotometric and spectrofluorometric titrations of 1 with triethylamine as well as with zinc(II) acetate are also reported.
