(1) Strictly speaking,polymerization isomerism,in which n varies in the complex [MLm]n is not isomerism.It is included in this list because it represents on additional way in which an empirical formula may give incomplete information about the nature of a complex.(2) For example,all members...
An empirical formula has been developed for determining the individual diameter of essentially unreflected cylinders in a critical planar array. The critical cylinder diameter, calculated by this formula, is within plusmn8% of the experimentally measured diameter for 112 experimental data points. ...
