摘要：

Crystallographic analysis is used to investigate the mutual packing arrangements of cluster groupings in the structures of KNa23O4(H2O)(48)[{Rh4O2(H2O)(2)}(H2W9O33)(2)] (I), (NH4)(2)[H3Mo57V6(NO)(6)O-183(H2O)(18)]center dot center dot 53H(2)O (II), and Na6Sr2[W12O40(OH)(2)]center dot 24H(2)O (III). It is found that all heavy cations in the clusters are located near the nodes of the single sublattice of the crystal. This arrangement ensures the coherence-assembly of the structural fragments since both the mutual orientation of the fragments and intervals between them are defined by the single cation sublattice.
