Abstract
The reaction (1:1) of BiCl3 and [18]aneS6 in acetonitrile provides colourless crystals of the adduct BiCl3.[18]aneS6. An X-ray crystal structure determination has revealed a BiCl3 pyramidal unit bonded to all six sulfur atoms of the macrocyclic ring which adopts an unusual S-shaped conformation. The bismuth atom sits on a crystallographically imposed three-fold axis in a nine-co-ordinate [3:3:3] geometrical arrangement involving two sets of three sulfur atoms and the three chlorine atoms respectively. Crystals are cubic, space group Pa3 with Z = 8 and a = 16.381 (5) angstrom; 1312 independent reflections were measured of which 825 with [I/sigma(I) greater-than-or-equal-to 2.0] were used in the final refinement, R = 0.044 (R' = 0.067), Bi-S 3.146(4) and 3.225(4) angstrom, Bi-Cl 2.607(4) angstrom and Cl-Bi-Cl 89.0(1)-degrees.
