Abstract
1,10-Phenanthrolinetris(4-methoxybenzoate)dysprosium, Dy(p-MOBA)3Phen (where p-MOBA = p-methoxybenzoate and Phen = 1,10-phenanthroline), (I) has been synthesized. The complex was characterized by various techniques including elemental analysis, UV, IR, XRD, molar conductance, and TG-DTG. The crystals consist of binuclear molecules and monoclinic, space group P2 1/n: a = 14.143(6) A, b = 17.550(7) A, c = 14.493(6) A, β = 117.357(4)°, Z = 2, ρ c = 1.655 g cm−3, F(000) = 1588; R 1 = 0.0176, wR 2 = 0.0455. In the complex, each Dy3+ ion is nine-coordinate to one 1,10-phenanthroline molecule, one bidentate chelating carboxylate group, and four bridging carboxylate groups in which the carboxylate groups are bonded to the Dy3+ ions in three modes: bridging bidentate, bridging tridentate, and chelating bidentate. The thermal decomposition mechanism of I has been determined on the basis of thermal analysis. In addition, the lifetime equation at a weight-loss of 10% was deduced as lnτ = −28.8361 + 19478.37/T by isothermal thermogravimetric analysis.
