Three new N2O heteroscorpionate ligands designated L60H, L70H and L90H, containing either appended hydrogen bond donating or accepting residues have been synthesized and characterized. Metal complexes of these ligands with Co(II) and Ni(II) have been characterized by X-ray crystallography. A facile decomposition pathway leading to C-N bond cleavage and isolation of metal pyrazole complexes was also identified. (C) 2003 Elsevier Ltd. All rights reserved.
