摘要: 二溴腈基乙酰胺具有很强的抗生、杀菌作用,其分子结构和晶体结构尚未见报道.本文合成并测定了该化合物的晶体结构,利用CNDO/2和INDO法计算了该化合物及2-腈基乙酰胺的内转动势垒.

关键词: 2, 2-二溴-2-腈基乙酰胺, 晶体结构, 内转动势垒

Abstract: The crystals of 2, 2-dibromo-2-cyanoacetamide are monoclinic, space guoup P21/n, a=0.6223 nm, 6=1.1309 nm, c=0.9744 nm, β=96.84°, Z=4; R = 0.072 for 1834 reflections.The rotation barriers around O = C-Csingle bond of 2-cyanoacetamide and dibro-mocyanoacetamide are calculated by CNEXD/2 and INDO methods.

Key words: 2,2-Dibromo-2-cyanoacetamide, Crystal structure, Rotation barrier
