Hydrogen-bonding patterns in the cocrystal 2-amino-4,6-dimethoxy­pyrimidine–anthranilic acid (1/1)

In the title cocrystal, C(6)H(9)N(3)O(2)·C(7)H(7)NO(2), the asymmetric unit contains two crystallographically independent 2-amino-4,6-dimeth­oxy pyrimidine-anthranilic acid adducts. The 2-amino-4,6-dimeth­oxy pyrimidine mol­ecules inter­act with the carboxylic group of the respective anthranilic acid mol­ecules through N—H⋯O and O—H⋯N hydrogen bonds, forming a cyclic hydrogen-bonded motif R (2) (2)(8). The pyrimidine mol­ecules also form base pairs via a pair of N—H⋯N hydrogen bonds, forming another R (2) (2)(8) motif. The typical intra­molecular N—H⋯O hydrogen bond is observed in the anthranilic acid mol­ecules. Furthermore, the crystal structure is stabilized by C—H⋯O hydrogen bonds.
