Molecular and Crystal Structures of Some Fluorocymantrenes

Abstract The crystal and molecular structures of the fluorocymantrenes [(C 5 H 4 F)Mn(CO) 3 ] 5−n F n )Mn (CO) 2 (PPh )] (n = 1–3) have been studied. influence phosphine for carbonyl substitution on bond parameters is larger than increasing fluorine content. In most cases Mn → P vector in a transoid position relative to substituents, therefore conformational PPh propeller are these very similar. show many intermolecular C–H⋯O hydrogen bonds only few C–H⋯F bonds.
