Comparison of sp-C-H...N Hydrogen Bond Lengths in Fluorinated and Nonfluorinated Ethynylbenzenes

Abstract

1,4-Diethynyltetrafluorobenzene was prepared and separately co-crystalized with 4,4'-bipyridine, 1,2-bis(4'-pyridyl)ethyne and trans-1,2-bis(4'-pyridyl)ethane to form 1:1 co-crystals that each contain essentially linear C-H...N hydrogen bonded ribbons of alternating diyne and dipyridine. The C-H...N hydrogen bond distances and angles in the 1:1 co-crystals are analyzed and compared to the previously reported C-H...N hydrogen bond distances and angles in the corresponding co-crystals formed with 1,4-diethynylbenzene.
