In situ cryocrystallization has been employed to grow single crystals of 4‐methoxybenzaldehyde (anisaldehyde), C 8 H 8 O 2 , 2‐hydroxybenzaldehyde (salicylaldehyde), C 7 H 6 O 2 , and (2 E )‐3‐phenylprop‐2‐enal (cinnamaldehyde), C 9 H 8 O, all of which are liquids at room temperature. Several weak C—H...O interactions of the types C aryl —H...O, C formyl —H...O and C sp 3 —H...O are present in these related crystal structures.
