| Abstract: Two lead complexes,[Pb(phen)(NO3)(H2O)]NO3 (1) and[Pb(phen)2(NO3)]NO3 (2) (phen=1,10-phenanthro-line) were synthesized via a solution synthesis method at room temperature. They were characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. In complex 1, the central metal Pb(Ⅱ) is tetra-coordinated to form a distorted tetrahedral geometry. In complex 2, the central metal Pb(Ⅱ) is hexa-coordinated to form a distorted octahedral geometry. By extensive intermolecular hydrogen bonds, complex 1 is connected into 1D chain supramolecular structure, while complex 2 is assembled into 3D supramolecular network. Complexes 1 and 2 have a strong inhibitory effect on Escherichia coli and Golden staph. The higher the concentration, the stronger the inhibitory effect. And the activity of complex 2 is superior to that of complex 1. |
