Jongh L.-A.d. ; Strasser C.E. ; Raubenheimer H.G. ; Cronje S. (2009)


The synthesis and structural characterisation (IR, MS, 1H, 13C and 15N NMR and single crystal X-ray diffraction analysis) of 2-aminoazole complexes of pentacarbonyl Cr(0) and W(0) are described. When provided with endocyclic soft thioether or endocyclic hard amine, endocyclic borderline imine and exocyclic hard amine coordination sites, the softer endocyclic imine coordination site is favoured. © 2009 Elsevier Ltd.
