In the framework of configurational model it is established that regions of existence of various forms of actinide hydroxocomplexes at variation of solution pH depend on differences of configuration energies and temperature. Saturation effect is found out, which leads to a sharp change of ligand concentration. Model of the polymerization of ionic groups UO$_2$[(OH)$_2$UO$_2$]$^{2+}_n$ into chain structure via hydrogen bonds is proposed. The thermodynamic stability of such a formation is investigated depending on the number of links at different temperatures and at various boundary conditions.
