Topochemistry. Part XXII. The crystal and molecular structures of trans,trans-muconodinitrile

Abstract

The crystal and molecular structures of trans,trans-muconodinitrile have been solved from 623 three-dimensional intensities measured with Cu k_α radiation on a G.E. goniostat, and corrected for absorption and secondary extinction; the structure was refined anisotropically in all atoms to r= 0·009, R= 0·039. The bond lengths, measured with an e.s.d. of 0·003 Å, are compared with corresponding values derived from previous analyses of other butadiene derivatives. The packing arrangement is discussed.
