摘　　要：合成了2 环己酮 1,3 二肟,并测定了该分子的晶体结构.晶体属单斜晶系,空间群为P21/c,晶胞参数:a=1.0255(2),b=0.5687(1),c=1.2953(3)nm,β=107.01(3)°,V=0.7223(2)nm3,Z=4,Dc=1.436g/cm3,F(000)=328.对于1286(I 2σ(I))个可观察点,最终偏差因子R=0.0623,wR=0.1769.整个分子呈蝴蝶型,两翼的二面角为25.7(3)°.由于分子间氢键的相互作用,晶体呈二维网状结构.The title compound 2cyclohexanone1,3dioxime, C6H8N2O3, Mr=156.14, crystallizes in the monoclinic system, space group P 21/c, with a=1.0255(2),b=0.5687(1),c=1.2953(3)nm,β= 107.01(3)°,V=0.7223(2)nm3,Z=4,Dc=1.436g/cm3, F(000)=328, final R=0.0623 and wR =0.1769 for 1286 observed reflections \. The molecule exhibits essentially butterflyshaped geometry with dihedral angle of 25.7(3)° between wings. The title compound is further linked into a twodimensional structure through the intermolecular hydrogen bonds of O-H...N.
