Abstract

Heterogeneous equilibria in the manganese perchlorate–urea–perchloric acid–water quaternary system at 25°С were studied by investigating solubility. The crystallization regions were determined for the initial solid components, eutonic compositions of ternary systems constituting the quaternary system, binary compounds of urea with manganese perchlorate and perchloric acid, and also two new coordination compounds containing simultaneously manganese perchlorate, urea, and perchloric acid: Mn(ClO4)2 · 4CO(NH2)2 · HClO4 and Mn(ClO4)2 · 2CO(NH2)2 · HClO4.
