Summary A series of metal ion complexes of the thiosemicarbazone, 3-azabicyclo[3.2.2]nonane-3-thiocarboxylic acid 2-[1-(6-methyl-2-pyridinyl)ethylidene]hydrazide (6 MLH) have been prepared and spectrally characterized. The ligand undergoes deprotonation to coordinatevia the thione sulphur, the imine nitrogen and the pyridyl nitrogen. A single anionic ligand such as Cl−, Br− and NO3 − completes the bonding to the CuII and NiII centre. The compound derived from CoCl2 contains two 6 MLH ligands bound to a CoII centre and a CoCl 4 2− counter ion. Complexes derived from perchlorate salts may feature 6 MLH, 6 ML, or both with the CoII being oxidized to CoIII. The solids were characterized by i.r., electronic and e.s.r. spectroscopy. In addition, electronic and e.s.r. spectra of their chloroform solutions were recorded.
