basis of IR, 1H, 13C and 11B spectral data and EI mass spectrometry. Antimicrobial activities of the semicarbazone ligands and their boron derivatives were investigated against E. coli and P. aeruginosa bacteria and A. niger and P. peniculosum fungi. B(OPri)3 and the boron semicarbazone derivative [(4-C6H4Cl)C(CH3)NN:C(NH2)OB(OC6H4O)] were used as precursors to synthesize nanosized cubic B2O3 (A and B)
