配合物的XPS光谱表明，氯掺杂物可以以三种化学状态存在。因此，以络合物的总氯平衡为基础的反应化学计量学可能会产生相当大的误导。从配合物的实际氯阴离子含量和碱«补偿»后相应的去质子化吡咯氮的量来看，对应于配合物中25%氧化吡咯单位的反应化学计量更有利
XPS spectra of the complexes suggest that the chlorine dopant can exist in three chemical states. Thus reaction stoichiometries based on the total chlorine balance of the complex can be quite misleading. From the actual chloride-anion content of the complexes and the corresponding amount of deprotonated pyrrolylium nitrogens after base «compensation», a reaction stoichiometry corresponding to 25% oxidized pyrrole units in the complex is favored
