First evidence for two different m-h1-h1- and m-h1-h2- co-ordination modes of the P3C2But2 ring of [Fe(h5-P3C2But2)(h5-C5H5)] to a same cluster fragment: synthesis and characterisation of [Ir4(CO)10{[Fe(h5-P3C2But2)(h5-C5H5)}] and x-ray molecular structure of the m-h1-h2- isomer

First evidence for two different m-h1-h1- and m-h1-h2- co-ordination modes of the P3C2But2 ring of [Fe(h5-P3C2But2)(h5-C5H5)] to a same cluster fragment: synthesis and characterisation of [Ir4(CO)10{[Fe(h5-P3C2But2)(h5-C5H5)}] and x-ray molecular structure of the m-h1-h2- isomer

Investigation of the solution structures of [Ir4(CO)11L] (L = [Fe(eta5-P3C2Bu t2)(eta5-C5H 5)] (1) and [Fe(eta5-P3C2Bu t2)(eta5-P2C 3Bu t3)] (2) by 13C and 31P NMR spectroscopy showed that, at 163K, 1 exists in the form of two isomers with bridged and non-bridged structures, in a 1:0.15 ratio, respe...
