Constitutional Isomerism of BiW6Cl15: (BiCl)[W6Cl14] and (BiCl2)[W6Cl13]

Hans-Juergen Meyer

The compound (BiCl)[W6Cl14] was previously characterized as a product of the reduction of tungsten hexachloride with elemental bismuth. Another modification of BiW6Cl15 is now presented as (BiCl2)[W6Cl13], based on the results of an X-ray single crystal structure determination (space group P21/c, a = 1354.3(2) pm, b = 1234.4(2) pm, c = 1538.9(2) pm, and β = 118.76(1) °). The structure of (BiCl2)[W6Cl13] contains chains of [(W6Cl8i)Cl4aCl2/2a-a]- clusters bridged by chlorine atoms. The (BiCl2)+ counter ion exhibits two short Bi–Cl distances of 244.1(4) and 245.9(3) pm, respectively.
