2-Acetylfuran-2-furoylhydrazone complexes of some 3d-metal ions

Abstract

2-Acetylfuran-2-furoylhydrazone (1), [HL] reacts with metal ions to yield the complexes of two types, compounds [VO(HL)SO4] and M(HL)2Cl2 [M = CoII, NiII or CuII] and compounds M(L)2(H2O)2 [M = CoII, NiII or CuII], depending on the pH of the medium. These complexes have been characterized by elemental analyses, molar conductance, magnetic susceptibility, visible, e.s.r. and i.r. spectral studies. Square pyramidal geometry for [VO(HL)SO4] and octahedral geometry for the remaining complexes are proposed.[Figure not available: see fulltext.] © 1986 VCH Verlagsgesellschaft mbH.
