Abstract
The structural model proposed previously for calcium dibarium bis(hydrogenp hosphate) bis(dihydrogenphosphate) from X-ray powder data is confirmed by t he present single-crystal study. The structure consists of infinite [Ca(HPO 4)(2)(H2PO4)(2)] anionic chains built up from CaO6, HPO4 and H2PO4 polyhedr a linked via Ca-O-P bonds. These chains are held together by nine-coordinat e Ba2+ cations. A two-dimensional, network of hydrogen bonds contributes to the linkage of these chains.
