Bis(1-methyl-piperazine-1,4-diium) di-?-bromido-bis-[tetra-bromido-bismuthate(III)] dihydrate.


ABSTRACT: In the title hydrated salt, (C5H14N2)2[Bi2Br10]·2H2O, the com-plete [Bi2Br10](4-) biocta-hedron is generated by crystallographic inversion symmetry. The diprotonated piperazine ring adopts a chair conformation, with the methyl group occupying an equatorial position. In the crystal, the tetra-anions and water mol-ecules are linked by O-H?Br and O-H?(Br,Br) hydrogen bonds to generate [100] chains. The chains are crosslinked by N-H?Br, N-H?O and C-H?Br hydrogen bonds originating from the piperazinediium dications, thereby forming a three-dimensional network.
