Description
Summary:The molecular structures of [RuH(dppp)2]+ (1) and [RuH{OC(CH3)2}(dppe)2]+ (2) ions in the PF6− salts were determined by the X-ray crystallography. 1 involves the agostic interaction between the ortho C–H bond of a phenyl group of the dppp ligands and the formally unsaturated Ru center, and takes the cis geometry, where the terminal hydride and the agostic C–H moiety occupy the adjacent sites to each other. 2 adopts a typical octahedral six-coordinate structure with a coordinating acetone molecule trans to the hydride.
