Abstract

The crystal and molecular structures of two reaction products of geminal dicyano oxiranes with thiohydantoione and thioxobenzoxazole have been determined from Mo-K„ X-ray diffraction data. The two reaction products were: 2H-2-(p-tolyl)-imidazo[l,2-b]thiazole-3,6-dione (compound I) and Z-3-benzoxazole-3-phenyl-2-oxo-2-propanenitrile (compound II) with the following crystal data at 293(1) K: Compound I, C12H10N2O2S, monoclinic P2i/c, a = 15.057(3), 6 = 5.200(3), c = 14.724(4) Å, f = 104.24(3)°, Z = 4; final R and Rw values were 0.034 and 0.049 for 1647 observed reflexions. Compound II, C16H10N2O2, monoclinic, P2]/n, a = 14.396(3), b = 4.326(1), c = 21.335(4) Å,yS = 107.79(1)°, Z = 4; finalR andPw values 0.040 and 0.053 for 1516 observed reflections.
