3-羟基吡啶，C5 H5 NO，晶体属单斜晶系，空间群P2 ljc，α = 7.709（3），B = 7.067（3），c = 17.989（6）A，β = 99.5（2）°，δ = 8。通过直接方法从自动衍射仪数据解出结构，并通过最小二乘技术对958个观察到的反射进行精修至R = 0.046（RFW = 0.059）。不对称单元的两个分子在其几何形状方面显示出显著的差异。分子通过短氢键O-H连接成无限长的链。. . N = 2.665。
3-Hydroxypyridine, C 5 H 5 NO, crystallizes in the monoclinic space group P2ljc with α = 7.709(3), b = 7.067(3), c = 17.989(6) Α, β = 99.5(2)° and Ζ = 8. The structure was solved from automated diffractometer data by direct methods and refined by least-squares techniques to R = 0.046 (RFW = 0.059) for 958 observed reflections. The two molecules of the asymmetric unit show significant differences with regard to their geometry. The molecules are connected to infinite chains by short hydrogen bonds Ο — Η . . . Ν of 2.665 Ä.
