Syntheses and structures of piperazin-1-ium ABr₂ (A = Cs or Rb): hybrid solids containing 'curtain wall' layers of face- and edge-sharing ABr₆ trigonal prisms.

ABSTRACT: The isostructural title compounds, poly[piperazin-1-ium [di-μ-bromido-caesium]], {(C₄H₁₁N₂)[CsBr₂]} _n , and poly[piperazin-1-ium [di-μ-bromido-rubidium]], {(C₄H₁₁N₂)[RbBr₂]} _n , contain singly-protonated piperazin-1-ium cations and unusual ABr₆ (A = Cs or Rb) trigonal prisms. The prisms are linked into a distinctive 'curtain wall' arrangement propagating in the (010) plane by face and edge sharing. In each case, a network of N-H⋯N, N-H⋯Br and N-H⋯(Br,Br) hydrogen bonds consolidates the structure.
