Usage

General Description

White crystals or white chunky solid.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

An organometallic. Strongly reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases. Organometallics containing halogens (fluorine, chlorine, bromine, iodine) bonded to the metal typically with generate gaseous hydrohalic acids (HF, HCl, HBr, HI) with water.

Fire Hazard

Flash point data for DIMETHYL TIN DIFLUORIDE are not available; however, DIMETHYL TIN DIFLUORIDE is probably combustible.

Safety Profile

Poison by intravenous route. See also TIN COMPOUNDS and FLUORIDES. When heated to decomposition it emits toxic fumes of F-.

Method for making dimethyltin difluoride

A method is disclosed for making dimethyltin difluoride by reacting dimethyltin dichloride with an alkali metal or ammonium fluoride salt.

Synthesis and M?ssbauer and vibrational spectra of some new tin(IV)-fluorine compounds

The solvolysis of methyltin(IV)-chlorine compounds of the general type (CH3)nSnCl4-n, with n ranging from 0 to 4, is studied in aqueous and anhydrous hydrogen fluoride under a variety of conditions. The studies in anhydrous HF have resulted in the synthesis of the new compounds methyltin(IV) trifluoride, dimethyltm(IV) chloride fluoride, and methyltin-(IV) dichloride fluoride. A convenient route to SnCl2F2 is found in addition. Interaction of this compound with either S2O6F2 or ClOSO2F results in the formation of SnF2(SO3F)2. Structural proposals for these compounds are based on infrared, Raman and 119Sn M?ssbauer spectra. All new compounds are found to be polymeric via fluorine or fluorosulfate bridges, resulting in penta- or hexacoordination around tin. Signs of the electric field gradients in these and some related compounds are deduced. Dialkyltin(IV) fluorides are easily obtained when the corresponding chlorides are solvolyzed in aqueous hydrogen fluoride.
