稀土氧化物和卤化铜与异烟酸(HINA)、吡啶-2，3-二羧酸(H_2pdc)或1，2-苯二甲酸(H_2bdc)的水热反应合成了三种新的稀土-铜(I)异金属化合物，分别为[Ce2(Ina)5(NA)2(H2O)2][Cu5Br4](1，na=烟酸)，[Er4(Ina)8(Bdc)2(OH)(H2O)5][Cu8I7](2)和[Ce3(Ina)8(Bdc)(H2O)4][Cu7Br6](3)。化合物1由Ln-有机双链和无机[Cu5Br4]nn+链两个不同的单元构成。化合物2由二维Ln-有机层和一维[Cu8I7]nn+原子链组成。化合物3可以看作是一个1D[Cu6Br6]n链状基序插入到三维Ln-Cu-有机基序的通道中。化合物1-3表现出三个不同的一维无机铜(I)-卤化物链与金属-有机一维链、二维层和三维网状结构相互连接，形成了三个混合基元的非互穿异金属铜-卤化物-稀土(Ln)-有机骨架，这是一个很好的例子和一种简单的方法来构建这种混合基元的异金属化合物。此外，还研究了1-3的IR、TGA和UV-Vis光谱。
Hydrothermal reactions of lanthanide(III) oxide and copper halide with isonicotinic acid (Hina) and pyridine-2,3-dicarboxylic acid (H2pdc) or 1,2-benzenedicarboxylic acid (H2bdc) lead to three novel lanthanide(III)-copper(I) heterometallic compounds, namely, [Ce2(ina)5(na)2(H2O)2][Cu5Br4] (1, na=nicotinic acid), [Er4(ina)8(bdc)2(OH)(H2O)5][Cu8I7] (2), and [Ce3(ina)8(bdc)(H2O)4][Cu7Br6] (3). Compound 1 is constructed from two distinct units of the Ln-organic double chains and inorganic [Cu5Br4]nn+ chains. Compound 2 consists of 2D Ln-organic layers and 1D [Cu8I7]nn+ cluster chains. Compound 3 can be viewed as a 1D [Cu6Br6]n chainlike motif inserted into the channels of a 3D Ln-Cu-organic motif. Compounds 1-3 exhibit three different 1D inorganic copper(I)-halide chains interconnected with metal-organic 1D chains, 2D layers, and 3D nets resulting in three mixed-motif non-interpenetrating heterometallic Cu-halide-lanthanide (Ln)-organic frameworks, which represent good examples and a facile method to construct such mixed-motif heterometallic compounds. Furthermore, the IR, TGA, and UV-vis spectra of 1-3 were also studied.
