中文摘要: |
6-氯-N,N-二甲基嘧啶-4-胺被合成得到,并经过IR、1H NMR和X-单晶衍射对化合物进行了表征。晶体结构显示化合物属正交晶系, Pbca 空间群, 晶胞参数为a = 10.922(2)?, b = 7.386(3) ?,c = 17.861(6) ?。在标题化合物的晶格内,存在着潜在的C-H???N和C-H???Cl两类分子间弱相互作用力,这些作用力的存在使化合物形成了二维网络结构,化合物变得更加稳定。。 |
英文摘要: |
6-chloro-N,N-dimethylpyrimidin-4-amine has been obtained and characterized by IR、1H NMR and X-ray single crystal diffraction. Crystal structure study shows that the title compound belongs to orthorhombic crystal system, Pbca space group with the unit cell parameters being a = 10.922(2)?, b = 7.386(3) ? and c = 17.861(6) ?. In the crystal lattices of the title compound, there exist two types of potential weak intermolecular interactions of C-H???N and C-H???Cl, which make the compound form 2-D networks and help to stabilize the molecular structure.. |
