چکیده
In the title compound, [Gd(C(15)H(11)O(2))(3)(C(17)H(18)N(2))], the Gd(III) atom is coordinated by six O atoms from three β-diketonate ligands and two N atoms from a chiral ligand L(S),(S)-(+)-7,7-dimethyl-3-(2-pyrid-yl)-5,6,7,8-tetra-hydro-6,8-methano-iso-quinoline, in a coordination geometry best described as distorted square-anti-prismatic.

In the title compound, [Tb(C(15)H(11)O(2))(3)(C(17)H(18)N(2))], the 7,7-dimethyl-3-(2-pyrid-yl)-5,6,7,8-tetra-hydro-6,8-methano-iso-quin-oline (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-diphenyl-propane-1,3-dione (dbm) ligands, forming enanti-omerically pure [Tb(dbm)(3)L(RR)]. The Tb(III) atom is ...
