✦ Synopsis


The asymmetric unit of the compound (NH 4 ) 7 (HPO 4 ) 2 (PO 4 ) consists of two hydrogen phosphate anions, one phosphate anion and seven ammonium cations, all of them located in general positions. The two [PO 3 (OH)] 2À anions are linked to the PO 4 3À anion via an O-HÁ Á ÁO hydrogen bond to form a three-anion unit, which is surrounded by the ammonium cations. The anions and cations are further connected via N-HÁ Á ÁO hydrogen bonding.
