Abstract:The co-crystal of perchlorates of ethylenediamine and triethylenediamine(ST)was prepared and characterized by 1H NMR and single crystal X-ray diffraction. The results revealed that the molar ratio of ethylenediamine against triethylenediamine in ST was 1∶1. The crystal belonged to orthorhombic system,space group Cmc21 with a=0.810 3(16)nm,b=2.472 5(5)nm,c=1.019 5(2)nm,V=2.042 5(7)nm3,Z=8,Dc=1.828 g cm-3,μ=0.67 mm-1. The co-crystal had super molecule structure. It is hydrogen bonding that joints triethylenediamine perchlorate and ethylenediamine perchlorate. The compound was zigzag chains and ethylenediamine involved in the formation of hydrogen bonding and triethylenediamine embedded in the gap. |
