Ionic complexes of the composition [LnL(2)(NO3)(2)](2)[Ln(NO3)(5)]3Me(2)CO (Ln = Sm (1), Eu (2), Tb (3), Dy (4)) with an optically active ligand L containing 1,10-phenanthroline and (+)-3-carene moieties are synthesized. According to the X-ray crystallographic data, the crystal structure of compound 2 is composed of complex [EuL2(NO3)(2)](+) cations (N6O4 polyhedron) and complex [Eu(NO3)(5)](2-) anions (O-10 polyhedron), and also Me2CO molecules. The L and NO3 ligands perform both tridentate and bidentate chelating functions respectively. Complexes 1-4 are isostructural and crystallize in the non-centrosymmetric space group P1; their magnetic properties are studied in the temperature range 2-300 K. The mu(eff) values for 1-4 at 300 K are 3.14 mu(B), 6.08 mu(B), 16.76 mu(B), and 18.30 mu(B) respectively and are typical of Ln(3+) ions. For complex 3 significant anisotropy results in a nonlinear field dependence of the magnetization at 2 K. Complexes 1-4 exhibit metal-centered orange (Sm3+), red (Eu3+), green (Tb3+), and yellow (Dy3+) luminescence in the solid state at room temperature. Luminescence quantum yield decreases for solid samples in the order 2 > 1 > 3 approximate to 4.
