Synthesis and Structures of Rare Earth 3-(4′-Methylbenzoyl)-propanoate Complexes-New Corrosion Inhibitors
Abstract
<p>A series of rare earth 3-(4′-methylbenzoyl)propanoate (mbp<sup>-</sup>) complexes [RE(mbp)<sub>3</sub>(H<sub>2</sub>O)] (RE≤rare earth≤Y, La, Ce, Nd, Ho, Er) have been prepared by either metathesis reactions between the corresponding rare earth chloride and Na(mbp) or protolysis of rare earth acetates by the free acid. Single-crystal X-ray diffraction studies of [RE(mbp)<sub>3</sub>(H<sub>2</sub>O)] (RE≤Ce, Nd) and [Ce(mbp)<sub>3</sub>(dmso)] reveal a 1D carboxylate-bridged polymeric structure in the solid state, featuring 9-coordinate rare earth ions. X-ray powder diffraction patterns of the bulk materials indicates that all of the [RE(mbp)<sub>3</sub>(H<sub>2</sub>O)] complexes except RE≤La are isomorphous. Hence, there is no structural change from the complex with RE≤Ce to that with RE≤Er despite the lanthanoid contraction. The <sup>1</sup>H NMR spectra of the RE≤Ho or Er complexes in (CD<sub>3</sub>)<sub>2</sub>SO show large paramagnetic shifts and broadening of the CH2 resonances, indicating the retention of substantial carboxylate coordination in solution.</p>
