摘要

A new metal-organic coordination polymer[Mn(NIPH)(phen)2]·4H20(1,H2NIPH=5-nitroisophthalic acid,phen=1,10-phenanthroline)has been hydrothermally synthesized and structurally characterized by elemental analyses,TG,IR spectroscopy and single-crystal X-ray diffraction.The complex crystallizes in monoclinic,space group P21 with a=1.082 2(2)nm,b=2.288 3(5)am,c=1.289 6(3)nm,β=105.11(3)°,V=3.083 2(11)nm3,wR=0.1345 for 4079 observed reflections (I>2o(I)).In the crystal structure,the manganese atom is six-coordinated with two carboxylate oxygen atoms from two different NIPH ligands and four nitrogen atoms from two phen ligands,showing a distorted octahedral geometry.Furthermore,it exhibits a 3D supramolecular network through hydrogen bonding and π-π stacking interactions.CCDC:818823.%通过水热法合成了1个新的金属一有机配位聚合物[Mn(NIPH)(phen)2]·4H2O(H2NIPH=5.硝基间苯二甲酸,phen=1,10-邻菲咯啉).并对其进行了元素分析、热重、红外光谱和X.射线单晶衍射测定.该配合物属于单斜晶系.P21空间群.晶体学数据:a=1.082 2(2)nm,b=2.288 3(5)am,c=1.2896(3)nm,β=105.11(3)°,V=3.083 2(11)nm3,C32H27MnN50lo'M=696.53,Dc=1.501 g·cm-3,μ(Mo Ka)=0.497咖-1,F(000)=1436,Z=4,最终R=0.0592,wR=O.1345用于4079个可观测点.在晶体结构中,锰原子为六配位与来自2个不同的NIPH配体上的2个羧基氧原子和来自2个phen配体上的4个氮原子配位.呈现畸变的八面体几何构型.而且该配合物通过氢键和π-π堆积作用扩展成三维超分子网状结构.
