【摘要】 在过去的几十年中,水热方法成功的应用于合成多金属氧酸盐化合物,具有越来越多的新奇结构多酸化合物被大量报道。多金属氧酸盐(POMs)是非常有趣和值得应用的经典的无机化合物。三个基于Strandberg结构阴离子与无机过渡金属相连的多酸化合物1-3,NaHH2[C12N4H20](P2Mo5023)Zn05[C12N4H18]·2H2O(1),NaH[C9N4H14](P2Mo5023)Co[C9N4H12]·4.5H20(2),[C9N4H14]2H2(P2Mo5023)·4H20(3)已经成功的应用水热方法被合成出来。应用单晶衍射和傅里叶红外光谱分析,获得化合物的结构。化合物1,是三斜的晶系,P2(1)的空间群,参数是a=12.330(3)A,b=14.368(3)A,c=15.069(3)A,α=111.02(3)°,β=90.33(3)°,γ=110.14(3)°,V=2314.0(8)A3。化合物2,是三斜的晶系,P2(1)的空间群,参数是a=11.7369(7)A,b=11.9799(7)A,c=17.2687(15)A,a=101.55(0)°,p=95.21(0)°,γ=112.23(0)°,V=2164.7(3)A3。化合物3,是斜方晶系,P2(1)的空间群,参数是a=22.6543(45)A,b=11.5411(23)A,c=15.1913(30)A,p=90.00(0)。,V=3971.85(137)A3。尽管化合物1-3有相同的多酸阴离子,但由于配体不同也导致化合物的结构不同。更多还原

【Abstract】 In the past several decades, polyoxometalates (POMs) have been hydrothermally synthesized. More and more novel structures were reported. Polyoxometalates (POMs) are a very interesting and useful class of inorganic compounds. All of these compounds contain the [P2Mo5O23]6-polyoxoanions as building units. Three of inorganic-organic complexes based on polymolybdate anions and transition metal-organic subunits, NaH2[C12N4H20](P2Mo5O23) Zn0.5[C12N4H18]·2H2O (1), NaH[C9N4H14](P2Mo5O23) Co [C9N4H12]·4.5H2O (2),and [C9N4H14]2H2(P2Mo5O23), have been synthesized under hydrothermal conditions and their crystal structures have been determined by single-crystal X-ray diffraction analysis, and FT-IR spectra for this compound were determined.1crystallizes were in the triclinic space group P21/2with a=12.330(3) A, b=14.368(3) A, c=15.069(3) A, a=111.02(3)°, β=90.33(3)°,γ=110.14(3)°, V=2314.0(8) A3;2crystallizes were in the triclinic space group P21/2with a=11.7369(7) A, b=11.9799(7) A, c=17.2687(15)A, a=101.55(0)°, β=95.21(0)°,γ=112.23(0)°, V=2164.7(3)A3and3crystallizes were in the orthorhombic space group P21/33with a=22.6543(45) A, b=11.5411(23)A, c=15.1913(30) A, β=90.00(0)°, V=3971.85(137) A3. Although compounds1-3contain similar polyoxometalate anions, the mean structures are slightly different, due to their different ligands.更多还原
