Popis:	From changes of positional parameters for Ba +2 and O −2 in lattice of YBa 2 Cu 4 O 8 and for Nd +3 in lattice of Nd 2 CuO 4 under pressure and during cooling the changes of cation charges are determined using the model of Coulomb interlayer interaction. The observed by crystal contraction interlayer charge transfer is caused by correlation of volume effects at cation charge change and assists to crystal contraction.
