✦ Synopsis

Some new types of mononuclear derivatives, AlL(1-4)L(1-4)H (1a-1d) of aluminium were synthesized by the reaction of Al(OPr

) in 1 : 2 molar ratio in refluxing benzene. Reactions of AlL(1-4)L(1-4)H with hexamethyldisilazane in 2 : 1 molar ratio yielded some new ligand bridged heterodinuclear derivatives AlL(1-4)L(1-4)SiMe 3 (2a-2d). All these newly synthesized derivatives were characterized by elemental analysis and molecular weight measurements. Tentative structures were proposed on the basis of IR and NMR spectra ( 1 H, 13 C, 27 Al and 29 Si) and FAB-mass studies. Schiff base ligands and their mono-and heterodi-nuclear derivatives with aluminium have been screened for fungicidal activities. These compounds showed significant antifungal activity against Aspergillus niger and A. flavus.
