Özet

The crystal structure of the title compound, C25H26Br2N2O4S2 was determined by single crystal X-ra diffraction technique. The crystals are monoclinic, space group C 2/c, with a=20.7142(2) Angstrom b=11.7910(2) Angstrom, c- 10.6735(3) Angstrom, beta =98.549(2)degrees, V=2577.94(9) Angstrom (3), Z=4. The structure was solved by direct methods and refined by least-squares methods to a final R=0.046 for 1866 observed reflections with I>2 sigma (I). The title compound, displays disordered geometry around the Cl atom located almost on twofold axis. The nine-membered heterocylic ring is close to the half-chair conformation. The dihedral angle between phenyl rings is 34.2(1)degrees.
