| 2 | Supramolecular Assemblies of Three New Metronidazole Derivatives Constructed with Various Dihydroxy-benzoic Acids via Hydrogen Bonds显示文摘Metronidazole(MTZ)is an important antibiotic,which has been widely applied to cure protozoal and bacterial diseases for human beings or animals.Herein,three novel drug supramolecular crystals constructed by MTZ with 2.5-dihydroxy-benzoic acid(2.5-DHBA)(1),2.6-dihydroxy-benzoic acid(2.6-DHBA)(2)and 3,5-dihydroxy-benzoic acid(3.5-DHBA)(3),respectively,have been discovered.The hydrogen bonds of N-H…O(O-H…N).C-H…O and O-H…O play important roles in the 3D supramolecular framework formation for crystals 1-3.Interestingly.due to the vary locations of the substituent groups,the two-dimensional layers in crystals 1 or 2 are constructed via intermolecular hydrogen bonds between MTZ and 2,5-DHBA or 2.6-DHBA,while in crystal 3 water molecules play a significant role except the intermolecular hydrogen bonds between MTZ and 3,5-DHBA.In addition,five synthons of I R^22(8),ⅡR3(9)in crystal 1,ⅢR1(4),ⅣR2(8)in crystal 2 andⅤR2(7)in crystal 3 formed through various hydrogen bonds are founded in this work.Systematic studies of syntheses,crystal structures and thermal analysis are reported. | QU Huiqi PAN Longhai SUN Yuexin WANG Lei LI Yanyan ZHANG Mingjuan ZHANG Zhaoxiang LIN Haifeng | 2020 | Chemical Research in Chinese Universities2020，36，6： | 0 |
