4-二甲基氨基吡啶，C7 H10 N2）的晶体结构属于单斜晶系，空间群为P2 J η，a = 14.813（3），B = 7.604（2），c = 6.103（2），β = 93.2（2）°，θ = 4。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1137个观察到的反射进行精修至R = 0.072（RFW = 0.092）。在该分子中发现与芳香吡啶体系只有很小的偏差。二甲氨基和吡啶环平面之间的扭转角为7（1）°。与其他衍生物所获得的结果进行了比较。
4-Dimethylaminopyridine, C7H10N2) crystallizes in the monoclinic space group P2Jη with a = 14.813(3), b = 7.604(2), c = 6.103(2) Â, β = 93.2(2)° and Ζ = 4 . The structure was solved from automated diffractometer data by direct methods and refined by least-squares techniques to R = 0.072 (RFW = 0.092) for 1137 observed reflections. Only small deviations from the aromatic pyridine system are found in this molecule. Between the dimethylamino group and the plane of the pyridine ring the torsion angle is 7(1)°. The results are compared with those obtained for other derivatives.
