crystal structure%bifurcated intermolecular hydrogen bond%aromatic stock effect
The title compound(C13 H10N2OCl2,Mr=281.13)was synthesized and its crystal structure was determined by X-ray analysis.The crystal belongs to orthorhombic system,space group P22121 with a=4.589(1),b=9.725(1),c=14.385(1)A,V=642.0(7)0.0466,wR=0.1216 for 662 observable reflections with I ＞2σ(Ⅰ).In the crystal of the title compound,the molecule has a crystallographic two-fold axis through C(1)-O(1)bond of the molecular hydrogen bond to form a ribbon extending along the a axis and the aromatic stock effect exists.
