Isostructural series of [{Al(H2O)6}{Ln(pda)3}].10H2O: Synthesis, structure and photoluminescence

Crystal structures of two SmIII complexes with dipicolinate [DPA]2− ligands: comparison of luminescent properties of products obtained at different pH values

“…The luminescent characteristics can be explained by the fact that the formed lanthanide(III) complex with three [DPA] 2ligands coordinating to the central lanthanide(III) cation exhibits an almost perfect tricapped trigonal prism (TTP) coordination environment (Albertsson, 1970;Brayshaw et al, 1995;Kim et al, 1998;Li et al, 2019;Murray et al, 1990;Salaam et al, 2022;Zhou et al, 1994). The luminescence properties have been studied in great depth; however, our knowledge of Sm III with [DPA] 2as the ligand is rather limited (Chuasaard et al, 2017;Kumar et al, 2019;Sharif et al, 2016;Viveros-Andrade et al, 2017).…”

Tris‐dipicolinate Lanthanide Complexes: Influence of the Second Hydration Sphere on the Solid‐State Luminescence Properties

“…These trisanionic complexes, of general formula [Ln(DPA) 3 ] 3present a threefold D 3 symmetry where the lanthanide ion is coordinated in an almost perfect trigonal tricapped geometry. Over the past 50 years, these tris-anionic complexes have been associated with a large variety of counter-cations such as alkaline (Li + , Na + , K + , Cs + ), [3] alkaline-earth (Mg 2+ , Ca 2+ , Ba 2+ ), [4] groups 3 and 13 trications (Sc 3+ , Al 3+ ) [5] but also cationic transition metal complexes 4 or ammoniums. [3a, 6] The nature of the counterion generally controls the crystal packing and ensures the structural diversity of the global architecture.…”

Synthesis and photoluminescence properties of polymer chains based on pre-designed heterometallic Al4Ln4 molecular rings

“…16,17 Ramanan et al isolated three photoluminescent aluminum hexamolybdates. 18,19 In recent years, the study of Al-Ln heterometallic clusters has become more systematic because of the development of aluminum oxo clusters (AlOCs). Zhang's team has constructed zigzag chains with optical and magnetic properties by introducing lanthanide ions into Al 4 polyanion clusters using stepwise assembly.…”
