Abstract

C18H15NO2, Mr = 277.3, monoclinic, P21/n, a = 7.408 (2), b = 22.311 (7), c = 8.613 (2) A, beta = 103.53 (3) degrees, V = 1384 (1) A3, Z = 4, Dx = 1.33 g cm-3, lambda(Mo K alpha) = 0.71069 A, mu = 0.94 cm-1, F(000) = 594, T = 293 K, 2229 unique diffractometer data, 963 with I greater than 3 sigma(I), R = 0.050. Structure solution was by the consistent electron density approach which combines the concepts of the OMIT map and density modification procedures. The benzolactam portion of the molecule is highly planar; most bond lengths and angles have typical values.

摘要

C18H15NO2,Mr = 277.3,单斜晶系,P21/n,a = 7.408(2),b = 22.311(7),c = 8.613(2)埃,β = 103.53(3)°,V = 1384(1)埃³,Z = 4,Dx = 1.33克/厘米³,λ(Mo Kα) = 0.71069埃,μ = 0.94厘米⁻¹,F(000) = 594,T = 293K,2229个独立衍射仪数据,963个I大于3σ(I),R = 0.050。结构解析采用了结合省略图和密度修正程序概念的一致电子密度方法。分子中的苯并内酰胺部分高度平面化;大多数键长和键角具有典型值。
