Neutral Adducts of Molybdenum Hexafluoride: Structure and Bonding in MoF₆(NC₅H₅) and MoF₆(NC₅H₅)₂.

ABSTRACT: The first Lewis acid base adducts of MoF₆ and an organic base have been synthesized, i. e., MoF₆(NC₅H₅) and MoF₆(NC₅H₅)₂. These adducts are structurally characterized with X-ray crystallography, showing that both adducts adopt capped trigonal prismatic structures. The MoF₆(NC₅H₅) and MoF₆(NC₅H₅)₂ adducts are fluxional on the NMR time scale at room temperature. Two different fluorine environments could be resolved by ¹⁹F NMR spectroscopy at -80 °C for the 1 : 2 adduct, MoF₆(NC₅H₅)₂, whereas MoF₆(NC₅H₅) remains fluxional at that temperature. D
