Abstract
- Sandwich-type lanthanide complexes with macrocyclic ligand cucurbit[6]uril (C36H36N24O12, CB[6]) were synthesized under hydrothermal conditions from aqueous solutions of lanthanide(lll) bromides, CB[6], and 4-cyanopyridine. According to X-ray analysis (Ln = La, Pr, Dy, Ho, Er, and Yb), the compounds with different structural types of lanthanide cores have a common fragment where the tetranuclear hydroxo complex is sandwiched between two macrocycles {(lN@CB[6])Ln4(μ3-OH)4(lN@CB[6])}6+ (IN = isonicotinate). The photoluminescence (for Ln = Eu) and Fourier transform ion cyclotron resonance mass spectra (for Ln = Pr, Dy, and Er) were studied. The compounds are used for the first time as precursors for the synthesis of lanthanide-silver heterometallic coordination polymers. The chainlike crystal structure of polymers (Ln = La, Pr, and Dy) is constituted by the sandwich complexes linked via the coordination of IN nitrogen atoms to the silver atoms. [ABSTRACT FROM AUTHOR]
