Hydroxylated phosphines as ligands for chalcogenide clusters: self assembly, transformations and stabilization

This contribution is a documentation of recent advances in the chemistry of chalcogenide polynuclear transition metal complexes coordinated with mono- and di-phosphines functionalized with hydroxo groups. A survey of complexes containing tris(hydroxymethyl)phosphine (THP) is presented. The influence of the alkyl chain in bidentate phosphines, bearing the P–(CH 2 ) x –OH arms, is also analyzed. Finally, isolation and structure elucidation of the complexes with HP(OH) 2 , P(OH) 3 , As(OH) 3 , PhP(OH) 2 , stabilized by coordination to Ni(0) and Pd(0) centers embedded into chalcogenide clusters, is discussed.
