A complete series of halocarbonyl molybdenum PNP pincer complexes - Unexpected differences between NH and NMe spacers.

ABSTRACT: In the present study a complete series of seven-coordinate neutral halocarbonyl Mo(II) complexes of the type [Mo(PNP^Me-Ph)(CO)₂X₂] (X = I, Br, Cl, F), featuring the new PNP pincer ligand N,N'-bis(diphenylphosphino)-N,N'-methyl-2,6-diaminopyridine (PNP^Me-Ph), were prepared and fully characterized. The synthesis of these complexes was accomplished by different methodologies depending on the halide ligands. For X = I and Br, [Mo(PNP^Me-Ph)(CO)₂I₂] and [Mo(PNP^Me-Ph)(CO)₂Br₂] were obtained by reacting [Mo(PNP^Me-Ph)(CO)₃] with stoichiometric amounts of I₂ and Br₂, respectively. Alternatively, these complexes were obta
