چکیده
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-dimeth-oxy pyrimidine-anthranilic acid adducts. The 2-amino-4,6-dimeth-oxy pyrimidine mol-ecules inter-act with the carboxylic group of the respective anthranilic acid mol-ecules through N-H⋯O and O-H⋯N hydrogen bonds, forming a cyclic hydrogen-bonded motif R(2) (2)(8). The pyrimidine mol-ecules also form base pairs via a pair of N-H⋯N hydrogen bonds, forming another R(2) (2)(8) motif. The typical intra-molecular N-H⋯O hydrogen bond is observed in the anthranilic acid mol-ecules. Furthermore, the crystal structure is stabilized by C-H⋯O hydrogen bonds.

In the title 1:1 adduct, C(6)H(9)N(3)·C(7)H(7)NO(2), the crystal structure is stabilized by hydrogen bonds involving two different R(2) (2)(8) motifs. One of them is formed by the inter-action of 2-amino-4,6-dimethyl-pyrimidine (AMPY) with the carboxyl group of anthranilic acid (AA) through N-H⋯O and O-H⋯N hydrogen bonds, whereas the other is formed through the inter-action of two centrosymmetr...

متن کاملSwitching the H-bonding network of a foldamer by modulating the backbone chirality and constitutional ratio of amino acids.
This communication describes the folding propensity of a heterofoldamer motif featuring proline (Pro) and anthranilic acid (Ant) residues in a 1:2:1 (α:β:α) constitutional ratio. Structural investigations unequivocally suggest that the hydrogen-bonding network of this foldamer motif can be switched between 9-membered and 6-membered by modulating the backbone chirality and constitutional ratio o...

متن کاملStructure and physicochemical characterization of a naproxen–picolinamide cocrystal
Naproxen (NPX) is a nonsteroidal anti-inflammatory drug with pain- and fever-relieving properties, currently marketed in the sodium salt form to overcome solubility problems; however, alternative solutions for improving its solubility across all pH values are desirable. NPX is suitable for cocrystal formation, with hydrogen-bonding possibilities via the COOH group. The crystal structure is pres...
