dc.description.abstract	1-(3,5-Dimethyl-3-nitro-1-pyrazolin-4-yl) penta-0-acetyl-o-galacto-pentitol, e20H29N 3012, Mr= 503·5, orthorhombic, P21212¡, a= 14·471 (9), b = 14·518 (3), e= 12·028 (2) A, V= 2527·0 (1·7) A3, z = 4, Dx = 1·323 Mg m- 3, .A(Mo Ka)= 0·7107 A, J.L = 0·1O mm- 1, F(OOO) = 1064, room temperature, final wR = 0·035 for 1836 observed reflexions. Bond distances and ang1es are all within the expected ranges. The pyrazoline ring exhibits approximate mirror symmetry and a puckering amplitude of 0·244 (6) A. Torsion angles of the acetoxy groups with the sugar chain range from 33 to 72°. Crystal cohesion is mainly due to van der Waals interactions but there are two intermolecular hydrogen bonds o108-2701/89/1o1563-03$03.00 linking molecules related by screw axes along [100] and [001].	es
