Abstract
The title compounds [Co4Na(H2O)][H(H2W12O42). 18H(2)O (I) and [Co-5(H2O)(22 )][H2W12O42]. 12H(2)O (II) were synthesized and their crystal structures de termined. The structures are built from paradodecatungstate anions joined b y Co and Na cations into three-dimensional networks. The Co and Na cations are coordinated both by O atoms of the anions and by water molecules. (C) 1 998 Elsevier Science S.A. All rights reserved.
