Coordination-driven self-assembly of oxalato-bridged half-sandwich p-cymene Ru complex [Ru2(μ-η4-C2O4)(MeOH)2(η6-p-cymene)2](O3SCF3)2 (1a) with several ditopic donors (La-Ld) in MeOH affords bi- and tetranuclear metallamacrocycles (2a and 3-5). Similarly, the combination of 2,5-dihydroxy-1,4-benzoquinonato (dhbq)-bridged binuclear complex [Ru2(μ-η4-C6H2O4)(MeOH)2(η6-p-cymene)2](O3SCF3)2 (1b) with a flexible bidentate amide linker (La) in 1:1 molar ratio gave the corresponding tetranuclear complex 2b. All the macrocycles were isolated as their triflate salts in high yields and were fully characterized by various spectroscopic techniques. Finally, the mol. structures of all the assemblies were determined unambiguously by single-crystal X-diffraction anal. The combination of acceptor 1a or 1b with an unsym. linear ditopic donor La results in a self-sorted linkage isomeric (head-to-tail) macrocycle (2a or 2b) despite the possibility of formation of two different isomeric macrocycles (head-to-head or head-to-tail) due to different connectivity of the donor. Mol. structures of the complexes 2a and 2b showed tetranuclear rectangular geometry with dimensions of 5.51 Å × 13.29 Å for 2a and 7.91 Å × 13.46 Å for 2b. In both cases, two binuclear RuII2 building blocks are connected by a μ-N-(4-pyridyl)isonicotinamide donor in a head-to-tail fashion. Surprisingly, the macrocycle 2a loses one counteranion and cocrystallizes with monodeprotonated 1,3,5-trihydroxybenzene via strong intermol. π-π stacking and H bonding. The tweezer complex 3 showed strong fluorescence in solution, and it showed fluorescence sensing toward nitroarom. compounds A fluorescence study demonstrated a marked quenching of the initial fluorescence intensity of the macrocycle 3 upon gradual addition of trinitrotoluene and exhibits significant fluorescence quenching response only for nitroarom. compounds compared to various other aromatic compounds tested. The experimental part of the paper was very detailed, including the reaction process of N-(Pyridin-4-yl)isonicotinamide(cas: 64479-78-3Related Products of 64479-78-3)
