Abstract: In the title compound, [Tb(C₁₅H₁₁O₂)₃(C₁₇H₁₈N₂)], the 7,7-dimethyl-3-(2-pyridyl)-5,6,7,8-tetrahydro-6,8-methanoisoquinoline (L^RR) ligand coordinates to Tb^III through the two N atoms of the heterocycle. The metal centre is also chelated by three deprotonated 1,3-diphenylpropane-1,3-dione (dbm) ligands, forming enantiomerically pure [Tb(dbm)₃L^RR]. The Tb^III atom is located in a distorted square antiprism of eight coordinating atoms (six O and two N atoms).
