| Popis: | Four new complexes of the general formula: (Ph 4 P) 2 [Sn(CH 3 ) 2 (RSO 2 N CS 2 ) 2 ], where Ph 4 P = tetraphenylphosphonium cation and R = CH 3 , ( 1 ), CH 3 CH 2 ( 2 ), C 6 H 5 ( 3 ), 4-FC 6 H 4 ( 4 ), were prepared by the reaction of the appropriate potassium N -R-sulfonyldithiocarbimates, K 2 (RSO 2 N CS 2 ), and tetraphenylphosphonium chloride with dimethyltin dichloride. The compounds 1 – 4 were characterized by 1 H, 13 C and 119 Sn NMR, 119 Sn Mossbauer, vibrational spectroscopy and by elemental analyses of C, H, N and Sn. The crystal structure of 1 was determined by X-ray diffraction techniques. The in vitro antifungal activity of the tin(IV) complexes were evaluated against the fungi Rhizoctonia solani and Botrytis cinerea by the Poisoned food test. The new compounds showed comparable activities to the fungicides manzate and ziram. |
