Weak C—H...O hydrogen bonds in anisaldehyde, salicylaldehyde and cinnamaldehyde
In situ cryocrystallization has been employed to grow single crystals of 4‐methoxybenzaldehyde (anisaldehyde), C8H8O2, 2‐hydroxybenzaldehyde (salicylaldehyde), C7H6O2, and (2E)‐3‐phenylprop‐2‐enal (cinnamaldehyde), C9H8O, all of which are liquids at room temperature. Several weak C—H...O interactions of the types Caryl—H...O, Cformyl—H...O and Csp 3—H...O are present in these related crystal structures.
