Synthesis, crystal structure, Hirshfeld surface, crystal voids, energy frameworks, DFT and molecular docking analysis of (2,6-dimethoxyphenyl)acetic acid

(2,6-dimethoxyphenyl)acetic acid exists in the triclinic crystal system having space group P-1 and lattice  dimensions = 7.66(4) Å, b = 8.16(4) Å, c = 8.65(3) Å, V = 503(4) Å3 and Z = 2. The molecular and crystal structure was elucidated using X-ray crystallographic techniques. The refinement of all the structural parameters was done using the full-matrix least-squares method and it yielded the final R-factor as 0.0579 for 1711 observed reflections. In the crystal packing, molecules are consolidated by intermolecular O-H....O and intramolecular C-H....O interactions. The O-H….O interaction makes a dimer corresponding to R22 (8) graph-set motif. Hirshfeld surface (HS) analysis has been complemented to envisage the conformity of the molecular structure. The void-volume analysis has been made to obtain the mechanical strength of the crystal structure. The energy frameworks have been constructed to know the stability of the structure and the kind of dominant energy present in it. The optimized structure using density functional theory (DFT), HOMO–LUMO energy and the charge on the atoms has been examined using B3LYP method. The inhibitory activity of (2,6-dimethoxyphenyl)acetic acid against microbial targets has been assessed using the docking process.
