C–H···π interactions in ethynylbenzenes: the crystal structures of ethynylbenzene and 1,3,5-triethynylbenzene, and a redetermination of the structure of 1,4-diethynylbenzene

Abstract

The crystal structures of 1,4-diethynylbenzene 1 and 1,3,5-triethynylbenzene 2 show similar packing principles with CH···π (triple bond)-zigzag networks; surprisingly, the packing motif of ethynylbenzene 3 is quite different.
