Abstract
Some Schiff’s base complexes of aluminum(III) of the type (CH3COCHCOCH3)2Al(µ-OPri)2AlLn(OPri)2-n [where LH=OHC(R)=CHC(R′)=NC6H5; R=R′=CH3,C6H5; R=CH3, R′=C6H5; LH=C6H4(OH)CH=NC6H5 and n=1 or 2] were prepared and characterized by various spectroscopic techniques. The molecular weight measurements indicated their binuclear nature. The 27Al nuclear magnetic resonance spectra of representative compounds [(CH3COCHCOCH3)2Al(µ-OPri)2Al{OC(C6H5)=CHC(C6H5)=NC6H5}(OPri)] [3] and [(CH3COCHCOCH3)2 Al(µ-OPri)2Al{OC(CH3)=CHC(CH3)=NC6H5}2] [6] suggest the presence of aluminum(III) atoms in different coordination states.
