Crystal structure of CsCrAs(2)O(7), a new member of the diarsenate family

Caesium chromium(III) diarsenate(V), CsCrAs(2)O(7), was prepared by solid-state reactions. The title structure consists of isolated CrO(6) octa­hedra and As(2)O(7) diarsenate groups, sharing corners to build up a three-dimensional [CrAs(2)O(7)](−) anionic framework. In this framework, channels exten...

Descripción
Sumario:Caesium chromium(III) diarsenate(V), CsCrAs(2)O(7), was prepared by solid-state reactions. The title structure consists of isolated CrO(6) octa­hedra and As(2)O(7) diarsenate groups, sharing corners to build up a three-dimensional [CrAs(2)O(7)](−) anionic framework. In this framework, channels extending parallel to [001] are present in which the ten-coordinate Cs(+) ions reside. CsCrAs(2)O(7) is isotypic with the monoclinic A (I) M (III) X (2)O(7) (A (I) = alkali metal; M (III) = Al, Cr, Fe; X = As, P) type I family of compounds crystallizing in the space group P2(1)/c.
