摘要：
The crystal and molecular structure of a ribavirin acyclic analogue, 1-(2-hydroxyethoxymethyl)-1,2,4-triazole-3-carboxamide, has been determined by X-ray diffraction method. The space group is P.hivin.1, unit cell parameters: a = 5,237(1), b = 6,960(1), c = 11,483(2) .ANG. .alpha. = 93,89(1), .beta. = 97,43(1), .gamma. = 94,26(1).degree.; Z = 2. The structure was solved by the direct method and refined by least-squares procedure to R = 3,7%. Two molecular conformers statistically coexist in the unit cell, differing in the hydroxyethoxymethyl group of conformation. Trans-conformation about 04''.sbd.C4'' bond and gauche about C4''.sbd.C5'' bond are observed in both molecules. C1''.sbd.O4'' bond is approximately perpendicular to the aglicon.
