摘要：

Tetrasodium cerium(IV) bis[diarsenate(4-)] is built from CeO8 antiprisms and AS(2)O(7) diarsenate groups connected by Ce-O-As mixed bridges to form a three-dimensional framework. The AS(2)O(7) diarsenate groups have a nearly eclipsed conformation. The framework delimits interconnecting tunnels running along the [001] and [110] directions where the Na+ cations are located.
