A novel coordination mode for a phospholyl ligand: μ-phosphindolyl-κ²P:P-μ-1-phenyl-phosphindolyl-κ²C²:P-bis[tetracarbonylmanganese(I)]

Abstract

The title compound, [Mn2(C8H6P)(C14H11P)(CO)8], displays a novel coordination mode for a phospho­lyl ligand, where dinuclear coordination is observed through the P atom and the adjacent C atom of the heterocycle.

Synthesis and Characterization of Benzo[b]phosphaferrocene Derivatives

“…In addition, benzannelation on the phospholide anion dramatically decreases its ability for π coordination. For example, benzophospholides 5 and dibenzophospholides 9 tend to act as σ donors, occasionally bridging two metal centers (e.g., 7 and 10 ), ,, and the η 5 coordination of dibenzophospholides 9 has never been reported to date . The latter is a clear contrast to the η 5 coordination capability of fluorenyl anions 8 .…”
