... le crystal x-ray analysis as well as by elemental analysis. Results: The title compound crystallized in monoclinic form with space group P21/c of a = 11.6050 (3) Å, b = 13.3130 (4) Å, c = 9.9884 (3) Å, β = 94.911 (2)°, V = 1537.52 (8) Å3, Z = 4 and Rint = 0.033. The pyridine ring formed dihedral angles of 74.1(3) and 88.2(5)° with major and minor components of disordered benzene ring, respectively. In the crystal packing, molecules were linked via intermolecular NConclusion: The title compound represents a good lead for the development of potent antibacterial agent against Gram positive bacteria and MRSA strains.
