The title compound, (C 3 H 12 N 2 )[H 2 AsO 4 ] 2 , contains a network of propane-1,3-diaminium cations and dihydrogenarsenate anions [mean As-O = 1.682 (2) A ˚]. The crystal packing involves anion-to-anion O-HÁ Á ÁO hydrogen bonds, resulting in double chains of dihydrogenarsenate tetrahedra. Cation
The title salt, (C 4 H 12 N 2 ) 2 [Bi 2 Cl 10 ]Á3H 2 O, was prepared by reaction of bismuth trichloride and piperazine in a hydrochloric acid medium. It consists of piperazinium dications and dimeric [Bi 2 Cl 10 ] 4À tetraanions, the latter with twofold rotation symmetry, together with water of crys
