 Title    Reactions of (SCN )2 with SnX4 (X = B r, I) A utönom a, Canto B lan co, Madrid 3 4 , Spain  
 Abstract    Fro m the reaction between (S C N)2 and Snl4 a compound is formed the formula o f which is IS n (N C S)3-I2, in which I2 m olecules form charge-transfer com plexes with thiocyanate groups. IS n (N C S)3 can be isolated from this com pound. Both compounds were characterised by m eans of elem ental analyses and U V -visible, IR and 119Sn M össbauer spectra, and a polym er structure with thiocyanate bridges was deduced. The equilibrium constant was calculated for the reaction: IS n (N C S)3-I2(solid) + CS2^± IS n (N C S)3(so lid)+ I2(solution) K = 2 . 2 ± 0 . 3 x l 0 -3 mol I-1 , and it was found that the two solid com pounds form a single phase. S nBr4 forms an unstable addition com pound with (S C N)2, which decom poses even below 0 °C.
