Bis(diethylammonium) Tetrachlorodivinylstannate(IV)

The Sn atom in the anion of the title compound, (C₄H₁₂N)₂[SnCl₄(C₂H₃)₂], exists in a distorted trans-C₂SnCl₄ octahedral geometry. Differences in Sn-Cl separations within the anion are related to hydrogen bonding between the Cl(2) atoms of the anion and the diethylammonium cations. The average Sn-Cl distance in this and related compounds is correlated with the Lewis acidity of the diorganotin moiety.
