R 6-complexation

Copolymer 35, generated from 19 and 8, was the first transition metal containing organometaHic polymer including one metal as a r 6-complex and the other as a r 5-complex.67 The remarkable terpolymer, 37, which contains r 4-(diene)iron, T]5-(cyclopentadienyl)man-ganese, and T)6-(styryl)chromium species in each chain, was made. Thermal decomposition in air was conducted to see if mixed metal oxide particles of novel composition could be generated, but characterization of these products was beyond our capabilities in 1972.
