| 摘要: 基于水热技术，合成了多金属氧酸盐修饰的2种新的过渡金属配合物[Cu（dmbipy）2（SiW12O40）][Cu（dmbipy）（H2O）3]·3H2O（1）和{（Hdmphen）2[Ag2（dmphen）2（SiW12O40）]}n（2）（dmbipy=4，4’-二甲基-2，2’-联吡啶，dmphen=2，9-二甲基-1，10-菲咯啉）。配合物1的最小不对称单元包含2种不同的Cu（Ⅱ）单元，其中Cu（Ⅱ）离子都采用了五配位的模式，并且水分子也参与了配位。氢键将不同的Cu（Ⅱ）单元连接形成了一维链，并延伸至二维层。在配合物2中，多金属氧酸盐连接Ag（Ⅱ）离子形成一维链。氢键和π…π堆积作用将一维链拓展成了二维层。 |

| Abstract: By utilizing two kinds of simply rigid organic ligands, two new polyoxometalates-modified transition metal compounds (POMs-TMC),[Cu(dmbipy)2(SiW12O40)] [Cu(dmbipy)(H2O)3]·3H2O(1), and {(Hdmphen)2[Ag2(dmphen)2(SiW12O40)]}n(2) (dmbipy=4,4'-dimethyl-2,2'-bipyridine, dmphen=2,9-dimethyl-1,10-phenanthrolin), were synthesized through hydrothermal technique. In compound 1, there are two crystallographically independent Cu(Ⅱ) ions. They all exhibit penta-coordinated modes, with three water molecules embedding through Cu-O bonds. Different Cu(Ⅱ) subunits cross-link each other to build a 1D chain by hydrogen bonding interactions between coordinated water molecules and[SiW12O40]4- anions. Adjacent chains also pursue to construct a 2D layer by such hydrogen bonding. In compound 2, the Keggin anions are fused by Ag(Ⅱ) ions to form a 1D chain. The adjacent chains are further linked by π…π stacking and hydrogen bonding interactions. So, 2D polyoxometalates-modified organic layer is constructed. The main traits of compounds 1 and 2 are that these simply rigid organic ligands employ noncovalent interactions to form the 2D layer. CCDC:1033952, 1; 1053009, 2. |
