Abstract
For 51 terminal alkyn groups in 42 crystal structures, the correlation of displacement parameters with C–H ⋯ X hydrogen-bond distances shows that thermal vibrations are reduced due to hydrogen bonding even for long C ⋯ X separations between 3.6 and 3.8 Å and H ⋯ X separations between 2.6 and 2.8 Å.
