Abstract
A new ternary mixed ligand dinuclear samarium(III) complex, Sm2(C3H3O2)6(phen)2 (1) (C3H3O2 = acrylate; phen = 1,10-phenathroline), has been synthesized and characterized by microanalysis, IR and UV/vis spectra and single crystal X-ray diffraction. Compound 1 crystallizes in the triclinic space group P1̅ with cell parameters: a = 9.6687(19), b = 10.690(2), c = 10.799(2) Å , α = 105.50(3), β = 106.67(3), γ = 91.59(3)°, V = 1023.8(3) Å3. The Sm(III) cations are bridged by four acrylate anions into a dinuclear molecular unit. The nine-coordinate Sm(III) atoms adopt a significantly distorted monocapped anti-square-prismatic geometry. Within the crystal structure, the complex molecules are associated via π-π stacking interactions into one-dimensional supramolecular chains along the [011] direction. Compound 1 exhibits intense fluorescence in the solid state at room temperature.
