4.Polymerization isomerism(聚合异构) (1)Strictly speaking,polymerization isomerism,in which n varies in the complex [MLm],is not isomerism.It is included in this list because it represents an additional way in which an empirical formula may give incomplete information about the nature of a complex. (2)For example,all members of the following series are polymerization isomers: Co心表目 [Co(NH3)3(NO2)3] n=1 [Co(NH3)6][Co(NO2)6] n=2 [Co(NH3)4NO2)2][Co(NH3)2NO2)4] n=2 [Co(NH3)5 (NO2)][Co(NH3)2(NO2)4]2 n=3 [Co(NH3)6][Co(NH3)2(NO2)4]3 n=4 [Co(NH3)s (NO2)]:[Co(NO2)6]2 n=5 30
