Tris(dibenzoylmethanido-κ2O,O′)[(6R,8R)-(−)-7,7-dimethyl-3-(2-pyridyl)-5,6,7,8-tetrahydro-6,8-methanoisoquinoline-κ2N,N′]terbium(III)
Abstract
In the title compound, [Tb(C15H11O2)3(C17H18N2)], the 7,7-dimethyl-3-(2-pyridyl)-5,6,7,8-tetrahydro-6,8-methanoisoquinoline (LRR) ligand coordinates to TbIII 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)3LRR]. The TbIII atom is located in a distorted square antiprism of eight coordinating atoms (six O and two N atoms).
