The crystal structures of two organometallic complexes of a new 2,9-diformylphenanthroline bis-acylhydrazone hexadentate ligand

The new potentially hexadentate ligand (2,9-diformylphenanthroline) bis(benzoyl)hydrazone (H2L) is synthesised and spectroscopically characterised. It reacts with dibutyltin diacetate and diphenyllead dichloride giving the complexes [(C4H9)(2)SnL] and [(C6H5)(2)PbL], respectively; their X-ray structure and spectroscopic characterization are reported.
