Abstract: | Stable solid adducts of silicon tetrafluoride with the following thiazoles have been prepared: 2-aminothiazole, 2-amino-5-methylthiazole, 2-amino-6-methylbenzothiazole, 2-amino-7-nitrobenzothiazole and 2,4-dimethylthiazole. These adducts have been charactertsed by chemical and infrared spectral analysis. In all the cases except that of 2,4-dimethylthiazole (SiF4·2L) the composition is 1:1. Both exocyclic and endocyclic nitrogen atoms are the coordinating centres in all the four cases while only endocyclic participates in coordination in the case of 2,4-dimethylthiazole. No indication has been found for the involvement of sulphur in coordination. Probable structures of these adducts have been proposed in which silicon is hexacoordinate. |
