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(Si W12O40)][Cu(dmbipy)(H2O)3]·3H2O(1)和{(Hdmphen)2[Ag2(dmphen)2(Si W12O40)]}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。
Based on hydrothermal technique, two novel transition metal complexes [Cu (dmbipy) 2 (Si W12O40)] [Cu (dmbipy) (H2O) 3] · 3H2O (1) (Dmpipy = 4,4’-dimethyl-2,2’-bipyridine, dmphen = 2,9-dimethyl- 1,10-phenanthroline). The smallest asymmetric unit of complex 1 contains two different Cu (Ⅱ) units, in which the Cu (Ⅱ) ions adopt a five-coordinate mode and the water molecules are also involved in coordination. Hydrogen bonds link different Cu (II) units into one-dimensional chains and extend to two-dimensional layers. In complex 2, the polyoxometalates connect Ag (II) ions to form a one-dimensional chain. Hydrogen bonds and π ... π stacking effect extend the one-dimensional chain into a two-dimensional layer.
