Abstract

In the title compound, C7H5ClO2.C3H7NO, the carboxyl­ic acid group of 4-chloro­benzoic acid is hydrogen bonded to a mol­ecule of N,N-di­methyl­form­amide via an R22(7) O - HO/C - HO motif. This motif takes precedence over the R22(8) O - HO dimer arrangement observed in 4-chloro­benzoic acid itself.
