Luminescence and Magnetic Properties of {LnIIICdII16} Metallacrown Complexes Centered with Compressed Tetragonal Antiprismatic Ln(III) Units
Metallacrown (MC) motifs are suitable elements for constructing functional lanthanide complexes, taking advantage of their versatile structural configurations and chemical tailoring capabilities. Herein, “triple-decker sandwich” MCs [LnCd16(quinha)16py8](NO3)2(CF3SO3)·20H2O·5DMF (1-Ln, Ln = DyIII, YbIII, and NdIII) have been synthesized using the quinaldichydroxamic acid (H2quinha) ligand. Structural analysis indicates that 1-Ln comprises two [12-MCCd(II)-4] rings coordinated with LnIII on the upper and lower sides and an outer [24-MCCd(II)-8] macrocycle. 1-Ln possesses a compressed tetragonal antiprismatic coordination geometry with zenithal angles over 65°. 1-Yb and 1-Nd exhibit near-infrared emission with lifetimes of 23.55 and 7.12 μs, and the abnormal temperature-dependent intensity might be caused by the hot band absorption. 1-Dy displays fast magnetization relaxation in the low-temperature region due to the inappropriate crystal field environment.
期刊介绍：
The aim of Crystal Growth & Design is to stimulate crossfertilization of knowledge among scientists and engineers working in the fields of crystal growth, crystal engineering, and the industrial application of crystalline materials.
Crystal Growth & Design publishes theoretical and experimental studies of the physical, chemical, and biological phenomena and processes related to the design, growth, and application of crystalline materials.
