Popis: 22-Membered mercuraazametallamacrocycles 6, 7, and 12 have been synthesized by dipodal condensation (2 + 2) of bis(o-formylphenyl)mercury (11) and 1,2-disubstituted amines. Reduction of macrocycle 6 with sodium borohydride afforded novel 11-membered mercuraazametallamacrocycle 13. Macrocycle 6, when treated with [Cu(CH3CN)4]ClO4 and Cu(OCOCH3)2/NH4PF6, formed orange-colored CuI complexes 14 ([6·Cu]ClO4) and 15 ([6·Cu]PF6), respectively, whereas red-colored complex 16 ([12·Cu]ClO4) was obtained from the reaction of 12 with [Cu(CH3CN)4]ClO4. Similarly, complexes 17 ([6·Ag]ClO4) and 18 ([6·Ag]PF6) were synthesized by the reaction of 6 with the corresponding silver salts. The reaction of 6 with Hg(OCOCH3)2/NH4PF6 led to the formation of hydroxo-bridged complex 19. The reaction of macrocycle 7 with Pd(C6H5CN)2Cl2 gave access to novel complex 9a. The macrocycles and the complexes have been characterized by elemental analysis, NMR (1H, 13C, 199Hg), fluorescence spectroscopy, and cyclic voltammetry. The molecular...
