X-ray studies on [NH3(CH2)5NH3]BiBr5 show that it crystallizes in the orthorhombic P212121 space group with the following unit-cell dimensions: a = 7.9580(4)Å, b = 14.0110(16)Å, c = 14.0960(14)Å. The structure was refined to R = 0.0492. It consists of penthylenediammonium cations and one-dimensional [BiBr5]n2- polyanionic zig-zag chains composed of deformed BiBr6 octahedra connected by two cis vertices. These chains are themselves interconnected by means of the N-H…Br hydrogen bonds.
