利用简单的手性有机配体L-酒石酸成功地合成出了一系列类似DNA螺旋构型的左、右旋的一维链状聚合物:{A[Mo2ⅥO4LnⅢ(H2O)6(C4H2O6)2].4H2O}n(Ln=Sm,Eu,Gd,Ho,Yb,Y;C4H2O6=L-或D-酒石酸;A=NH4或H3O).通过水热法,巧妙地把传统的钼氧单核{MoO4}、双核{Mo2O7}以及{Mo8O26}等结构单元,通过有机配体配位的过渡金属单元交错地连接成零、一、二、三维的一系列结构新颖的化合物,这类化合物大多数具有可以容纳客体小分子的隧道或空穴,如[Cu(4,4′-bpy)]2MoO4.2H2O,[Cu(4,4′-bpy)]2Mo2O7,[Cu(4,4′-bpy)(Hnic)(H2O)]2Mo8O26等.首次利用水热法合成出了含稀土的杂多酸类化合物,[Gd(H2O)3]3[GdMo12O42].3H2O.该化合物是由Silverton型的[GdMo12O42]9-阴离子和配位的Gd3+阳离子组成的.在[GdMo12O42]9-离子中首次把顺磁性的钆(Ⅲ)离子引入到该构型的中心,并且通过九配位的钆(Ⅲ)离子把它们连接成具有介孔结构的三维网状化合物.该化合物的获得为今后合成类似化合物提供了一个很好的范例.在水热法合成出的化合物[Cu2(C8H6N2)2(C7H6N2)]2[Mo8O26]中,首次捕捉到喹喔啉的氧化产物苯并咪唑,证明了在水热条件下含氮的芳香杂环类的有机配体可以被二价铜氧化,其氧化产物进而作为配体直接与铜原子配位,最终形成新颖的上述化合物.
A series of left-dextrorotary one-dimensional chain-like polymers with similar DNA helix structure were successfully synthesized by using simple chiral organic ligand L-tartaric acid: {A [Mo2VIO4LnⅢ (H2O) 6 (C4H2O6) 2]. 4H2O} n (Ln = Sm, Eu, Gd, Ho, Yb, Y; C4H2O6 = L- or D-tartaric acid; A = NH4 or H3O). By hydrothermal method, the traditional molybdenum oxygen mononuclear {MoO4 }, Binuclear {Mo2O7} and {Mo8O26}, etc. A series of novel compounds with zero, one, two and three dimensions are alternately connected via transition metal units coordinated by organic ligands. Most of these compounds have A tunnel or hole containing small guest molecules such as [Cu (4,4’-bpy)] 2MoO4.2H2O, [Cu (4,4’-bpy)] 2Mo2O7, [Cu (4,4’-bpy) (Hd) 3 (H2O)] 2Mo8O26, etc. The rare earth-containing heteropolyacid compounds [Gd (H2O) 3] 3 [GdMo12O42] .3H2O were synthesized by hydrothermal method for the first time.The compounds were synthesized from [GdMo12O42] 9-anion and a complexing Gd3 + cation. Paramagnetic gadolinium (III) ions are first introduced into the center of this configuration in [GdMo12O42] 9- ions, They are linked into a three-dimensional network of mesoporous structures The synthesis of the compound provides a good example for the synthesis of similar compounds in the future.In the compound [Cu2 (C8H6N2) 2 (C7H6N2)] 2 [Mo8O26] synthesized by hydrothermal method, the oxidation products of quinoxaline Benzimidazole. It is proved that the organic ligands of aromatic heterocycles containing nitrogen in hydrothermal conditions can be oxidized by divalent copper, the oxidation products of which are coordinated directly to the copper atoms as ligands to finally form novel compounds.
