(a) [SnF5]− has a polymeric structure consisting of chains with cis-bridging F atoms. Draw a repeat unit of the polymer. State the coordination environment of each Sn atom, and explain how the overall stoichiometry of Sn : F = 1:5 is retained in the polymer.
(b) Which of the salts PbI2, Pb(NO3)2, PbSO4, PbCO3, PbCl2 and Pb(O2CCH3)2 are soluble in water?
(c) The IR spectrum of ClCN shows absorptions at 1917, 1060 and 230 cm−1. Suggest assignments for these bands and justify your answer.
