When hexaiodobenzene reacts with diferrocenylzinc, the most interesting product is obtained in, alas, only 4% yield. This compound contains no elements other than those that are in ferrocene. Moreover, its formula has a C/Fe atom ratio exactly ten percent higher than in ferrocene and an H/Fe atom ratio ten percent lower than in ferrocene. Predict (and sketch) this product. Why is it interesting? (Y. Yu, A. D. Bond, P. W. Leonard, U. J. Lorenz, T. V. Timofeeva, K. P. C. Vollhardt, G. D. Whitener, A. A. Yakovenko, Chem. Commun. , 2006 , 2572.)
