dc.description.abstract | The present study involves the synthesis, structure, and electrochemical properties of the phosphine derivatives of C<sub>60</sub>-metal cluster (triosmium, Trirhenium and Tetrairidium) complexes. In chapter 1, study of the new trirhenium-C<sub>60</sub> phosphine derivatives has been described. The treatment of $Re<sub>3</sub>(μ-H)<sub>3</sub>(CO)<sub>9</sub>(μ<sub>3</sub>-η<sup>2</sup>:η<sup>2</sup>:η<sup>2</sup>-C<sub>60</sub>)$ (II-1) with 2.2 equiv of $Me<sub>3</sub>NO$ in the presence of excess $PMe<sub>3</sub>$ in chlorobenzene (CB) gave the bisphosphine-substituted $1,2-Re<sub>3</sub>(μ-H)<sub>3</sub>(CO)<sub>7</sub>(PMe<sub>3</sub>)<sub>2</sub>(μ<sub>3</sub>-η<sup>2</sup>:η<sup>2</sup>:η<sup>2</sup>-C<sub>60</sub>)$ complex as two diastereomers, II-2a (major, 38 %) and II-2b (minor, 11 %). The corresponding reaction of II-1 with 3.3 equiv of Me3NO, produced the trisphosphine-substituted isomeric product $1,2,3-Re<sub>3</sub>(μ-H)<sub>3</sub>(CO)<sub>6</sub>(PMe<sub>3</sub>)<sub>3</sub>(μ<sub>3</sub>-η<sup>2</sup>:η<sup>2</sup>:η<sup>2</sup>-C<sub>60</sub>)$ as two diastereomers, II-3a (major, 37 %) and II-3b (minor, 15 %). Complexes II-2a and II-3b have been characterized by spectroscopic methods and elemental analyses. Single crystal X-ray diffraction studies were obtained for II-2a and II-3b, despite their diastereomeric fluxionality. The hydrides were confirmed by 1H NMR spectroscopic method and directly located only for II-3a by X-ray diffraction. The molecular structure of II-2a confirms a face-capping $μ<sub>3</sub>-η<sup>2</sup>:η<sup>2</sup>:η<sup>2</sup>-C<sub>60</sub>$ ligand with one axial and one equatorial $PMe<sub>3</sub>$ ligand on adjacent rhenium atoms, whereas that for II-3b exhibits pseudo-Cs symmetry with an additional equatorial $PMe<sub>3</sub>$ on the third rhenium atom. Molecular structures for II-2b and II-3a are proposed by axial $PMe<sub>3</sub>$ ligand placement and subsequent equatorial $PMe<sub>3</sub>$ placement, based on ... | eng |
