Actinide complexes iodates

The solution reactions of Cm3+ closely resemble those of the lanthanide and actinide +3 ions, and the fluoride, oxalate, phosphate, iodate, and hydroxide are insoluble. Complexes appear to be weaker than those of preceding elements. 

Salts of 0x0 anions, snch as nitrate, snlfate, perchlorate, iodate, hydroxide, carbonate, phosphate, oxalate, and so on, are important for the separation and reprocessing of technologically important actinides, while hydroxide, carbonate, and phosphate ions are important for the chemical behavior of the actinides in the enviromnent. The general trends of complexes formed in aqneons solntions are as follows ... 

Cm(iii) is a class A or hard metal ion and thus complexes far more strongly to oxygen and fluoride donors than to more polarizable donors such as chloride or sulfur. Solution reactions of Cm resemble those of the trivalent lanthanides and actinides. The fluoride, oxalate, phosphate, iodate, and hydroxide are essentially water-insoluble and the chloride, iodide, perchlorate, nitrate, and sulfate are water-soluble. The first hydrolysis constant for Cm ", i.e. for the reaction ...
