Heating with NaH in solution gives A , which has the empirical formula C₇H₆O₂Fe. A reacts rapidly at room temperature to eliminate a colorless gas B , forming a purple-brown solid C having the empirical formula C₇H₅O₂Fe. Treatment of C with iodine generates a brown solid D with the empirical formula C₇H₅O₂FeI, which on treatment with TlC₅H₅ gives a solid E with the formula C₁₂H₁₀O₂Fe. E , on heating, gives off a colorless gas, leaving an orange solid F with the formula C₁₀H₁₀Fe. Propose structural formulas for A through F .
