In the title co-crystal, C(22)H(14)O(4)·CH(4)N(2)O, the 1,1'-binaphthyl-2,2'-dicarboxylic acid (BNDA) and urea mol-ecules are connected via a system of hydrogen bonds into a chiral two-dimensional polymeric structure parallel to the (001) plane. As the crystal is centrosymmetric, it consists of alternately stacked BNDA-urea layers of opposite chirality. The urea H atoms trans to the C=O group are bonded in a chelating mode [R(1) (2)(6)] to the carbonyl O atom from one of the carboxylic acid groups which, in turn, acts as the donor of an O-H⋯O hydrogen bond to another urea mol-ecule.
