Abstract

Two mercury(II) complexes [(bmppa)Hg(ClO4)]ClO4 {1, bmppa = N,N-bis(2-methylthio)ethyl-N-[(6-pivaloylamido-2-pyridyl)methyl]amine} and [(beppa)Hg(ClO4)]ClO4 {2, beppa = N,N-bis(2-ethylthio)ethyl-N-[(6-pivaloylamido-2-pyridyl)-methyl]amine} of N2S2(thioether)O(amide)-donor chelate ligands have been prepared and characterized by X-ray crystallography and/or spectroscopic methods. In the solid state, the HgII ion of 2 exhibits an overall coordination number of six and strong amide oxygen coordination. Comprehensive multinuclear NMR studies of 1 and 2 have yielded the first Jmath image and Jmath image coupling constants associated with a Hg–RSCH3 methyl group. In the presence of one equivalent of Me4NOH·5H2O in methanol/acetonitrile solution, theamide appendages of 1 and 2 undergo alcoholysis. (© Wiley-VCH Verlag GmbH & Co.
