Summary
The chelating behaviour of neutral and deprotonated 2,6-diacetyl-pyridine bis(2-furoylhydrazone), H2dapf, has been investigated in some new complexes of oxovanadium(IV), manganese(II), cobalt(II), nickel(II), copper(II) and zinc(II). The hydrazone reacts with the metal salts to yield complexes of two types; the addition compounds [VO(H2dapf)]SO4, [M(H2dapf)Cl]Cl and the deprotonated complexes [M(dapf)H2O] [M=manganese(II), cobalt(II), nickel(II), copper(II) or zinc(II)] in neutral and alkaline media, respectively. The complexes have been characterized by elemental analyses, molar conductance, magnetic susceptibility, electronic, i.r. and e.s.r. studies and their stereochemistries are discussed.
