Abstract
Cobalt(II), cobalt(III), nickel(II), and copper(II) complexes with N-(2-furylmethyl)salicylideneaminates (abbreviated as X–sal–fum) were synthesized. In addition to the M (X–sal–fum)2 type complexes, those of the formula Cu (X–sal–fum) Cl were obtained in crystals. The complexes Co (X–sal–fum)3 are six-coordinate, octahedral. The cobalt(II) complex is four-coordinate, tetrahedral and the nickel(II) complexes are four-coordinate, planar. In these complexes, the ligands X–sal–fum function as bidentates, the furan oxygen atom not being bound to the metal ions. The results are compared with those reported previously for related ligands. It is most likely that the complexes Cu(X–sal–fum)Cl consist of binuclear complexes with spin-spin interaction between copper(II)ions.Keywords
