✦ Synopsis

New complexes of chromium(llI), manganese(lI) and nickel(ll) with methylhydrazinccarboxylate (MeCz) and of manganese(II) and nickel(II) with 1,1-dimethylhydrazinecarboxylate (MezCz) were prepared by reacting salts of the metals with CO2-saturated solutions of the hydrazines in EtOH. The compounds [Cr(MeCz)3].2H20, Ni(MeCz)2(H20)3 -MMH, Mn(MeCz)2(HzO)a(MMH = monomethylhydrazine) and M(Me2Cz)2(H20)2 (M = Mn or Ni) were investigated using d.t.a., t.g.a., electronic and i.r. spectroscopy and by magnetic susceptibility measurernents.

ESR and absorption spectra were measured for the square planar cobalt(II), nickel(II) and copper complexes with some I4, 15 and 16membered N4macrocyclic ligands, such as (14-a), H(14-b), H,(14c), HJIS-c) and H,(16-c) (for the abbreviations, see Fig. 2 in the text). On the basis of the ESR spectra of
