20.500.12556/DKUM-66670 The crystal and molecular structures of two reaction products of geminal dicyano oxirane with thiohydantoine (compound I) and thioxobenzoxazole (compound II) Kristalne i molekulske strukture dvaju reakcijskih produkata geminalnog dicijanooksirana s tiohidantoinom i tiooksobenzoksazolom The crystal and molecular structures of two reaction products of geminal dicyano oxiranes with thiohydantoione and thioxobenzoxazole have been determinated from ▫$Mo-K_\alpha$▫ X-ray diffraction data. The two reaction products were: 2H-2-(p-tolyl)-imidazol[1,2-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, ▫$C_{12}H_{10}N_2O_2S$▫, monoclinic ▫$P2_1/c$▫, a=15057(3), b=5.200(3), c=14.724(4) Å, ▫$\beta=104.24(3)°$▫, Z=4; final R and ▫$R_w$▫ values were 0.034 and 0.049 for1647 observed reflexions. Compound II, ▫$C_{16}H{10}N_2O_2$▫, monoclinic, ▫$P2_1/n$▫, a=14.396(3), b=4.326(1), c=21.335(4) Å, ▫$\beta-107.79(1)°$▫, Z=4;final R and ▫$R_w$▫ values 0.040 and 0.053 for 1516 observed reflections. Metodom röntgenske difrakcije ▫$Mo-K_\alpha$▫ određene su kristalne i molekulske strukture 2H2-(p-tolil)-imidazo[1,2-b]tiazol-3,6-diona, ▫$C_{12}H_{10}N_2O_2S$▫ (spoj I) i Z-3-benzoksazol-3-fenil-2-okso-2-propanonitrila, ▫$C_{16}H{10}N_2O_2$▫ (spoj II). Oba spoja kristaliziraju u monoklinskom sustavu.
