Abstract
The crystalline and molecular structure of 2-amino-5-phenyl-1,3,4-thiadiazo le was studied by the X-ray diffraction method. C8H7N3S. Monoclinic crystal s: a = 11.085(3), b = 7.544(3), c = 11.180(3) Angstrom; beta = 115.22(2)deg rees; V = 845.8(5) Angstrom (3); d(calc) = 1.404 g/cm(3); mu (MoKalpha) = 0 .325 mm(-1); Z = 4; space group P2(1)/c. Molecules of 2-amino-5-phenyl-1,3, 4-thiadiazole in crystal form dimers through intermolecular hydrogen bonds, which are arranged in infinite layers parallel to the xy plane.
