Sb2(C6F4)3 and Sb2(C6Cl4)3 can be synthesised simply by heating together 1,2-I2C6X4 (X = F, Cl) and powdered antimony in sealed tubes.Both compounds form hemi-solvates with a variety of organic solvents; typically, the weak hexane solvate of Sb2(C6F4)3 loses hexane slowly at room temperature.The mass spectra, and the 13C NMR spectrum of Sb2(C6F4)3, are described.Chlorine reacts with Sb2(C6F4)3 to give Sb2(C6F4)3Cl4 which, on boiling with water, forms the oxide Sb2(C6F4)3O2.Sb2(C6F4)3 is oxidised by concentrated nitric acid to the dinitrate Sb2(C6F4)3(OH)2(NO3)2 which slowly hydrolyses in aqueous solution to form the tetrahydroxo derivative Sb2(C6F4)3(OH)4.
