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 R 3 c , with a ?=?18.999(3), c ?=?11.915(3)?Å, V ?=?3724.6(12)?Å 3 , 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)?Å 3 , D c?=?1.840?Mg?m -3 , Z ?=?6, F (000)?=?2034 and R 1?=?0.0209. Photophysical properties of the complexes were investigated.
