The preparation and reactivity of a range of novel paramagnetic chromium(II) complexes supported by a carbazolebased PNP pincer ligand is reported. Deprotonation of the ligand precursors (R)(PNP) H (I-R) and subsequent reaction with chromium(II) chloride led to the formation of square-planar chlorido complexes (R)(PNP)CrCl (2(R)). Further reaction with various alkylating agents resulted in the isolation of chromium alkyl complexes R(PNP)CrR' (3(R)-R') which were then hydrogenated to yield two rare examples of paramagnetic chromium(II) hydrides 4(iPr) and 4(tBu). Both compounds were characterized by X-ray diffraction and paramagnetic NMR spectroscopy supported by a comprehensive DFT-supported assignment of the resonances. While the di(tert-butyl)phosphino PNP substituted complex 4(tBu) was found to exhibit a monomeric square-planar molecular structure, its isopropyl-substituted analog 4(iPr) forms a dimer, also indicated by a strong antiferromagnetic coupling of the chromium centers. The pronounced reactivity of these compounds toward C.X double bonds was demonstrated by reaction with benzophenone, N,N'-dicyclohexylcarbodiimide, and carbon dioxide, which gave the corresponding insertion products. The alkoxido complex 5(iPr,) the amidinato complex 6(iPr), and the formato compound 7tBu were also characterized by X-ray diffraction.
