摘要：

The title compound [Dy-2(C22H16ClN4O5)(3)](SCN)(3)(H2O)(CH3OH) has been synthesized and its crystal structure determined by single X-ray diffraction at room temperature. The two nine coordinated Dy(III) are bound to three macromolecules ligand through the pnenolic oxygens of the p-chlorophenol moieties, the nitrogen atoms and the carbonyl functions of the hydrazonic moieties. The phenolic oxygen atoms of the 2-hydroxybenzoyl groups are not bonded to the metal ions. In the bases of the coordination polyhedra the six Dy-N bonds are in the range 2.563(13)-2.656(13) Angstrom and the twelve Dy-O bonds are in the range 2.281(10)-2.406(10) Angstrom.
