The results show that they are four-coordinated. The preliminary bioassay reveals that they have good acaricidal activity and some of them have insecticidal, herbicidal activities at the same time.展开更多
A series of trihydrocarbyltin chlorides containing silicon was synthesized. The acaricidal activity was determined and the structure activity relationship was tried to be found out with the hydrophobic parameter.
