The structure was charac- terized by chemical analysis, elemental analysis and IR patterns. The single crystal structure was determined by X-ray single crystal diffraction. It crystallizes in monoclinic system, space group P21/n with a=2.107 9(4) nm, b= 1.482 0(3) nm, c=2.113 4(4) nm, β=93.44(3)°, Z=4, V=6.590(2) nm3, Dc=2.001 g·cm-3, μ=2.480 mm-1, F(000)= 3840, R1=0.0468, wR2=0.1163. The single crystal structure indicates that the four chlorines coordinated to the antimony atom forms a distorted triangle bipyramid configuration together with the lone electron pair on the Sb atom. The [SbCl4]- to 2-(3′-pyridyl)benzimidazole cation and Cl- by weak interaction forms the ionic crystal. It has been proved that the title compound has antibacterial activity. CCDC: 283824.展开更多

The amount of the adsorbed antimony by UPD and the dissolved antimony by anodic oxidation depends upon the potential applied. At potential greater than Eeq, antimony adsorbed atoms axe formed. As the potential becomes more positive,the amounts of the adsorbed antimony atoms decrease and a complete oxidative stripping occurs at a potential greater than 0.90V.It has been found that eath antimony adsorbed atom occupies three sites of platinum.展开更多
