Abstract

Abstract : The cover picture shows two isomers of [B9 H14 ] − which coexist in a crystalline salt, the mirror symmetric form on the left and the unsymmetrical form on the right. The structures interconvert in solution, but only the lower symmetry form has ever been observed in the solid state. Conformationally flexible 1‐butyl‐3‐methylpyrrolidinium counterions provide the interactions which stabilize both forms and allow them to co‐crystallize. Details are given in the Communication by R. D. Rogers et al. onpage 922 in Issue 9, 2016 (DOI:10.1002/cplu.201600270 ).
