✦ Synopsis

7,12,14,14-hexamethyl-1,4,8,11-tetraazacyclotetradecanenickel(II)

and -4,11-dienenickel(II) complexes (1-4) were studied by cyclic voltammetry. The thermodynamic stability of Ni III was the greatest in complex 4 with a trans configuration of the pendant amino groups. On acidification, the Ni II /Ni III redox process was not observed. After alkalisation the redox process was only reco-

The crystal structure of a copper(II) complex of 2acetylpyridine 3-piperidylthiosemicarbazone, [Cu(Acpip) 2 ], indicates a tridentate, monoanionic ligand (i. e., pyridine nitrogen, imine nitrogen and thiolato sulfur atoms) and a bidentate, monanionic ligand (i. e., imine nitrogen and thiolato sulfur
