Complexes with macrocyclic ligands. IV. Heterodinuclear cobalt(II), nickel(II), copper(II), zinc(II) and palladium(II) complexes with a macrocyclic ligand of Schiff-base type: Syntheses and structures [German]

摘要

The synthesis and properties of nickel(II), copper(II), and palladium(II) complexes, [MLPh] (3; L-Ph = N,N'-phenylene-bis(3-formyl-5-tert.-butyl-salicylaldimine)), are described. These neutral mononuclear complexes react with metal(II) perchlorate and 1,3-propylenediamine to form heterodinuclear, macrocyclic, cationic complexes of the type [MM'(L-Ph,L-3)](2+) (4; M = Ni, Cu, Pd; M' = Co, Cu, Zn). The structures of the five new compounds [NiCo(L-Ph,L-3)](ClO4)(2), [NiCu(L-Ph,L-3)](ClO4)(2), [CuCu(L-Ph,L-3)](ClO4)(2), [CuZn(L-Ph,L-3)](ClO4)(2), and [PdCu(L-Ph,L-3)](ClO4)(2) were determined by X-ray diffraction.
