analyses. Single crystal X-ray analyses reveal that the two Cu(II) complexes show different 2D coordination networks, the 4-connected (44·62) topology for complex 1 and the (4·62)2(42·62·82) topology for complex 2. In the 2D layers of complexes 1 and 2, the 3-dpyb ligands adopt a typical μ2-bridging mode (via ligation of two pyridyl nitrogen atoms), while 1,2,4-HBTC and SIP serve as a linear spacer and a ‘V’-like
两种新的二维金属有机配合物,即 [Cu(3-dpyb)(1,2,4-HBTC)(H2O)]·H2O (1) 和 [Cu3(3-dpyb)3(SIP)2(H2O) 8]·6H2O (2) [3-dpyb = N,N'-双(3-吡啶甲酰胺)-1,4-丁烷, 1,2,4-H3BTC = 1,2,4-苯三甲酸, H3SIP = 5 -磺基间苯二甲酸],已通过元素分析、IR、TG 和单晶 X 射线衍射分析进行水热合成和结构表征。单晶X射线分析表明,两种Cu(II)配合物显示出不同的二维配位网络,配合物1的4-连通(44·62)拓扑和(4·62)2(42·62·82)拓扑对于配合物 2。在配合物 1 和 2 的二维层中,3-dpyb 配体采用典型的 μ2-桥接模式(通过两个吡啶基氮原子的连接),而 1,2,4-HBTC 和 SIP 作为线性间隔区和一个“V”样的接头,分别,连接相邻的 Cu(II) 中心。相邻的
