【摘要】 以Zn(ac)2·2H2O、2,2’-联吡啶、H5[PMo10V2O40]·XH2O和NH4VO3为原料通过水热法合成了一种新型的有机-无机复合物[Zn(C10H8N2)3][HPMo12O40(VO)2],并用IR和X射线单晶衍射技术对其进行了表征。该复合物的晶体结构属于三斜晶系,空间群P-1,晶胞参数为α=1.149 55(4)nm,b=1.337 63(5)nm,c=1.500 68(6)nm,α=74.682(2)°,β=80.075(1)°,γ=87.910(2)°,V=2.192 17(14)nm3,Z=1,Dc=2.172 Mg·m-3,F(000)=1 350,μ(MoKα)=2.494 mm-1,R1=0.083 4,wR2=0.201 9。
【Abstract】 An organic-inorganic hybrid complex,[Zn(C10 H8N2)3][HPMo12 O40(VO)2]was synthesized hydrothermally and structurally characterized by IR and X-ray crystallography.The crystal belongs to triclinic,space grounp P-1,with a = 1.149 55(4) nm,b=1.337 63(5) nm,c = 1.500 68(6) nm,α = 74.682(2)°,β=80.075(1)°,γ=87.910(2)°,V=2.192 17(14) nm3,Z= 1,Dc=2.172 Mg · m-3,F(000) = 1 350,μ(Mo Kα) = 2.494 mm-1.The structure was refined to R1=0.083 4 and wR2 =0.201 9 for 3 330 observed reflections with I>2σ(I).Single crystal structure showed that the titlecompound was constructed from[HPMo12O40(VO)2]2- cluster anion and[Zn(C10H8N2)3]2+ metal-organic complex cation,and[Zn(C10H8N2)3]2+ combined with the heteropolyanion through electrostatic attraction,which was consistent with the IR spectroscopy.
