Abstract
Two new lanthanide coordination compounds, RE(ABA)3(H2O)3·H2O (RE = Sm, Dy; ABA = 3-aminobenzoate), were obtained from ethanol solution and characterized structurally by X-ray diffraction methods. Both possess a monomeric molecular structure. Complex 1, Sm(ABA)3(H2O)3, is rhombohedral, space group R3c, with a = 18.999(3), c = 11.915(3) Å, V = 3724.6(12) Å3, D c = 1.784 Mg m−3, Z = 6, F(000) = 2010, GOF = 1.133 and R 1 = 0.0204. Complex 2, Dy(ABA)3(H2O)3, is isomorphous, with a = 18.956(4), c = 11.812(3) Å, V =3675.8(14) Å3, D c = 1.840 Mg m−3, Z = 6, F(000) = 2034 and R 1 = 0.0209. Photophysical properties of the complexes were investigated.
