These complexes have the general formula [M(PMTHP)\-2en], where M=Cu(Ⅱ), Ni(Ⅱ), Co(Ⅱ), Pd(Ⅱ), Pt(Ⅱ). They were characterized by elemental analysis, IR, UV vis, magnetic moments and molar conductance. The results showed that the complexes are all of quadricoordinate square planar geometry. The antibacterial experiment indicated that they have high antibacterial activities against S. aureus, B. subtillis, E. coli, E. carotovora, C. flaccumfaciens.展开更多
The electronic structures of N,N′ bis[(1 phenyl 3 methyl 5 oxo 4 pyrazolinyl) α furylmethylidyne]ethylendii mine (and o phenylendiimine), and their complexes of transition metals M (M=Ni, Cu, Co, Pd, Pt) have been c...The electronic structures of N,N′ bis[(1 phenyl 3 methyl 5 oxo 4 pyrazolinyl) α furylmethylidyne]ethylendii mine (and o phenylendiimine), and their complexes of transition metals M (M=Ni, Cu, Co, Pd, Pt) have been calculated by B3LYP method of DFT. Their geometries and bonding characters are discussed, and the relationship between their bioactivities and electronic structures are also discussed from the calculated results of electronic populations and frontier orbital energies.展开更多
