The secondary phosphite selenide, CpFe(CO)2P(Se)(OiPr)2, as an organometalloligand in heterometallic M–Se–P–Fe(Cp)-type complexes [M = Cr(0), W(0), Pd(II), Pt(II), Au(I)]

Abstract

The neutral metalloligand [CpFe(CO)2P(Se)(OiPr)2] (Cp = η5-C5H5), which contains the rare secondary phosphite selenide moiety, reacts with different metal complex precursors to form six new heterobimetallic complexes containing M–Se–P–Fe(Cp) bond connectivity. The complexes [M(CO)5{CpFe(CO)2P(Se)(OiPr)2}] (M = Cr, 1; M = W, 2), [MCl2{CpFe(CO)2P(Se)(OiPr)2}2] (M = Pd, 3; M = Pt, 4), [Au4Cl4{CpFe(CO)2P(Se)(OiPr)2}2], 5, and [AuI{CpFe(CO)2P(Se)(OiPr)2}], 6, are all heterometallic, neutral, dinuclear (1, 2, 6), trinuclear (3, 4), and hexanuclear (5) complexes. The complexes were all prepared from straightforward substitution reactions (1–5) or as an adduct, 6. All new complexes were characterized by 1H, 31P, 77Se NMR, infrared spectroscopy, elemental analysis and single crystal X-ray diffraction.
