When hexaiodobenzene, C₆I₆, reacts with diferrocenylzinc, , one of the products has a C to Fe atom ratio exactly 10 percent higher than in ferrocene and an H to Fe atom ratio 10 percent lower than in ferrocene. The product contains no elements other than those that occur in ferrocene. Suggest a structure of this product. (See Y. Yu, A. D. Bond, P. W. Leonard, U. J. Lorenz, T. V. Timofeeva, K. P. C.
