(2,2,8,8-tetramethyl-5-oxa-4,6-diphospha-3,6-nonadiene)tetrakis[dicarbonyl(methylcyclopentadienyl)manganese], the first complexed bis(phosphavinyl) ether

Abstract

The title compound 1 is the complex of a novel ligand. It is formed from [(CH3C5H4)Mn(CO)2·thf] and (CH3)3C-C=P, presumably with uptake of H2O. The bis(phosphavinyl) ether in 1 functions as an 8-electron donor toward the four (CH3C5H4)Mn(CO)2 units (abbreviated here as Mn).
