Abstract

Two new tungsten oxide clusters compounds on Na1, and through the OW16···O7 (2.988Å) hydrogen bond connect into a three-dimensional network structure. We conducted infrared tests, thermogravimetric tests and two-dimensional infrared correlation spectroscopy tests on compounds 1 and 2, and set up control experiments to test the inhibitory effects of two compounds on two common pathogenic bacteria E. coli and Staphylococcus aureus in life, combined with two-dimensional infrared correlation spectroscopy (2D-IR COS) and thermogravimetric analysis, the sandwich-type compound 1 and compound 2 with the same configuration, the polarizability of Mn and Cu have a greater impact on the overall configuration, which may be directly lead to the different antibacterial effects of the both. Experimental tests and analysis show that the transition metals in the compound have a close influence on the inhibition of S. aureus.
