摘要：

Palladium(II) acetate reacts with butane-2,3-dione bis(octanoylhydrazone) (H(2)oct) giving a dimeric [Pd-2(oct)(2)] complex as main product; as shown by X-ray crystal analysis, the ligands are bideprotonated and in each of them one carbonyl oxygen and the two imine nitrogens are bonded to one palladium ion, whereas one hydrazide nitrogen is bonded to the second palladium, giving rise to a N3O square planar coordination. The core of the complex is constituted by an unusual six-membered PdN2PdN2 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 N2O2 square planar. Monomers are also the nickel(II) and palladium(II) complexes with butane-2,3-dione bis(thiobenzoylhydrazone) and phthalic dicarboxaldehyde bis(benzoylhydrazone). (C) 1999 Elsevier Science S.A.
