利用中温水热法合成了一种未见报道的一维超分子杂化物,(H2bbi)5(HP2Mo5O23)2(H2O)2[bbi=1,1’-(1,4-丁烷)双(咪唑)],通过元素分析、IR、单晶X-射线衍射对化合物的结构进行了表征.结果表明该化合物属于单斜晶系,P2(1)/c空间群;晶胞参数:a=17.253(5),b=21.169(5),c=25.397(5),β=104.537(5),Z=4,V=8979(4)3,R1=0.0383,wR2=0.0868.两个晶体学独立的Standberg型[HP2Mo5O23]5-阴离子和5个双质子化的bbi配体通过氢键作用拓展成一维超分子.此外,该固态化合物在室温下显示出蓝色的荧光性质.
A novel one-dimensional supramolecular hybrid (H2bbi) 5 (HP2Mo5O23) 2 (H2O) 2 [bbi = 1,1 ’- (1,4-butane) Imidazole)], the structure of the compound was characterized by elemental analysis, IR and single crystal X-ray diffraction. The results show that the compound belongs to the monoclinic space group P2 (1) / c; the unit cell parameter is a = 17.253 (5) , b = 21.169 5, c = 25.397 5, β = 104.537 5, Z = 4, V = 8979 43, R1 = 0.0383, wR2 = 0.0868. Two crystallographically independent Standberg-type [HP2Mo5O23] 5-anions and five bi-protonated bbi ligands expand into one-dimensional supramolecules by hydrogen bonding.In addition, the solid compounds exhibit blue fluorescent properties at room temperature.
