4,4'-Bis(di-n-butylaminostyryl)-2,2'-bipyridine: a space group revision

M. Bolte

Abstract: The structure of the title compound, C₄₂H₅₄N₄, has originally been refined in space group P1 (No. 1) with two molecules in the asymmetric unit. However, successful refinement clearly demonstrates that the structure is better described in space group P $\overline{1}$ (No. 2) with two half molecules in the asymmetric unit, both molecules being located on centres of inversion.
