Abstract

The title compound crystallizes in the monoclinic space groupP21/c. Twinning occurs between domains sharing thehk0 zone. The indices of imprecise intensity data were interpreted successfully. A subset of these data could be corrected and used in structure determination together with single-crystal intensity data of the predominant domain, whereas the remaining superposition data were excluded from refinement. Structure solution converged at satisfactory values ofR=0.082,R w=0.074. The structure consists of isolated Lewis acid base adducts.
