Nickel(II) and palladium(II) complexes with acylhydrazone ligands of α-diketones: the electronic and steric factors affecting the formation of the dimeric palladium(II) complexes
the complex is constituted by an unusual six-membered PdN 2 PdN 2 ring. The same arrangement is also found in [Pd 2 (ben) 2 ] (H 2 ben, butane-2,3-dione bis(benzoylhydrazone)) where the alkyl chains of the ligand H 2 oct are substituted by phenyl rings. On the contrary, the corresponding nickel(II) complexes are monomers and the coordination is N 2 O 2 square planar. Monomers are also the nickel(II)
