Abstract

The reaction of triindenyllanthanide complexes (C9H7)3Ln · THF (Ln = Nd, Pr) with equimolar 2-tetrahydrofurfuryl methanol in THF solution at room temperature forms two new binuclear diindenyllanthanide alkoxides, namely [(C9H7)2Ln(μ,η2-OCH 2CHCH2CH2CH2)] 2⌊O⌋ [Ln = Nd (1) and Pr (2)]. These two new complexes have been characterized by IR, MS spectra and metal analysis, indicating they are oxygen-bridging dimers. Complex 1 has also been studied by X-ray crystallography. The crystal structure of Nd complex revealed that the oxygen atoms of tetrahydrofurfuryl methoxide ligand act as both a bridging and a chelate donating group in the title complexes. The Nd atom is coordinated by two η5-C9H7 ring centroids, two oxygen atoms of tetrahydrofurfuryl methoxide ligands and an oxygen atom of tetrahydrofuran ring, indicating a nine coordination number. The Nd-C (η5-C9H7) distances range from 2.79(2) to 2.92(2) Å, averaging 2.81(2) A. The Nd-O(1) (μ-OR′) bond distances are 2.30(1) and 2.31(1) Å, averaging 2.305(1) Å. In the intramolecular five-membered chelating ring, the Nd-O(2) distance is 2.51(1) Å.
