合成了四种新的无机-有机杂化骨架化合物[Mn(L)(H2O)(2)](n)(1),{[Co(L)(H2O)(3)]中心点2 H(2)O-CH 3OH}(n)(2),{[Zn(L)(H2O)]中心点H2O)(3)和[Cd(HL)(2)](n)(4)[H2 L = 4-(异烟酰胺基)邻苯二甲酸]。配合物1具有与SrAl 2(sra)相关的三维(3D)结构和拓扑结构,Schlafli符号为(4(.)(2)6(3).8)。2为(3,3)-连接的二维网络,拓扑结构为(4.8(2)); 3为单结点(3,3)-连接的(6,3)二维网络,通过N-H中心点中心点中心点O氢键相互作用进一步连接,形成三维结构,拓扑结构为hms拓扑结构,Schlafli符号为(6(3))(6(9).8)。配体部分去质子化的配合物4也具有二维网状结构。此外,还研究了化合物1的磁性、化合物3的非线性光学性质以及化合物3和化合物4的光致发光性质。(C)2010爱思唯尔有限公司版权所有。
Four new inorganic-organic hybrid frameworks [Mn(L)(H2O)(2)](n) (1), {[Co(L)(H2O)(3)]center dot 2H(2)O-CH3OH}(n) (2), {[Zn(L)(H2O)]center dot H2O) (3) and [Cd(HL)(2)](n) (4) [H2L = 4-(isonicotinamido)phthalic acid] have been synthesized and characterized by single-crystal X-ray diffraction analysis. Complex 1 has three-dimensional (3D) structure and topology related to SrAl2 (sra) with Schlafli symbol of (4(.)(2)6(3).8). And 2 displays (3,3)-connected two-dimensional (2D) network with (4.8(2)) topology, while 3 exhibits a uninodal (3,3)-connected (6,3) 2D network, which is further linked by N-H center dot center dot center dot O hydrogen bonding interactions to give 3D structure with hms topology and Schlafli symbol of (6(3))(6(9).8). Complex 4 with partial deprotonated HL- ligands also has a 2D network structure. In addition, the magnetic property of 1, nonlinear optical property of 3 and photoluminescence of 3 and 4 were investigated. (C) 2010 Elsevier Ltd. All rights reserved.
