- Аннотация: The adduct compound was prepared by condensation of equimolar quantities of analar vaniline and 1-phenyl-2-amino pyrimidine in absolute ethyl alcohol. Prismatic crystals were obtained with the crystallographic data: a = 12.901(6), b = 19.297(9), c = 6.828(3)A,y = 102.67(2)", V= 1657.9 A3, Z = 4, F.W. = 291.31, D, = 1.17 g/cm3, space group P2/n, R = 0.038 and R, = 0.036. The intensity data were collected on an Enraf Nonius CAD-4 computer controlled diffractometer using MoKal radiation. The structure was solved by direct method and refined by full matrix least-squares using anisotropic temperature factor of all atoms, except for hydrogen ones, which were treated isotropically. A full discussion was given to explain: a) the occurrence of the condensation process between the OH-group of vaniline and the heterocyclic N-atom in position 5 of the pyrimidine cycle and b) why this condensation does not take place between the amino-group of the pyrimidine compound and the aldehydic group of vaniline to give a Schiff base.
