以苯并咪唑和MoO3等为原料合成得到一个含有Mo—N键的新型配合物H2[Hbim]2[(bim)2Mo8O26].H2O(bim代表苯并咪唑),并通过红外光谱和单晶X-射线衍射等方法确定了其晶体结构.结构分析表明:该晶体属于单斜晶系,P2(1)/n空间群.晶胞参数:a=1.388 2(14)nm,b=1.392 7(14)nm,c=1.594 0(16)nm,α=90°,β=107.334(12)°,γ=90°,V=2.942(5)nm3,Z=2,R1=0.052 5.该配合物由苯并咪唑和[Mo8O26]4-配位形成主体结构,苯并咪唑通过Mo—N键直接与[Mo8O26]4-相连,周围质子化的苯并咪唑阳离子和游离的H+作为反荷离子平衡电荷.
A novel complex H2 [Hbim] 2 [(bim) 2Mo8O26] containing Mo-N bond was synthesized by using benzimidazole and MoO3 as raw materials. H20 (bim represents benzimidazole) was synthesized and characterized by IR and single crystal X Ray diffraction. The structural analysis shows that the crystal belongs to the monoclinic space group P2 (1) / n with unit cell parameters of a = 1.388 2 (14) nm and b = 1.392 7 ( 14 = nm, c = 1.594 0 (16) nm, α = 90 °, β = 107.334 (12) °, γ = 90 °, V = 2.942 Benzimidazole and [Mo8O26] 4- are coordinated to form the host structure. Benzimidazole is directly linked to [Mo8O26] 4 through Mo-N bond. The surrounding protonated benzimidazolium cation and free H + Balance the charge.
