✦ Synopsis

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 crystallization. Hydrogen-bond interactions, including N-HÁ Á ÁO, N-HÁ Á ÁCl and O-HÁ Á ÁCl interactions, stabilize the crystal structure.

In the title compound, (C 5 H 14 N 2 ) 2 [Bi 2 Cl 10 ]Á2H 2 O, each Bi III atom of the centrosymmetric anion is six-coordinate in a distorted octahedral geometry. The salt adopts a threedimensional network arising from the hydrogen bonds between the cations, anions and water molecules.
