摘  要:合成了一种单核锰配合物[Mn2(C16H13O3)4(H2O)8]·2H2O(C16H13O3为酮洛芬阴离子),并且对该化合物进行了元素分析、红外、PXRD、热重、荧光及单晶X射线衍射表征。标题配合物属于三斜晶系,P1空间群,a=0.867 42(4)nm,b=0.897 47(3)nm,c=2.194 13(9)nm,α=92.207(3)°,β=99.615(4)°,γ=108.738(3)°,V=1.587 03(11)nm3,Z=4,R=0.044 9。Mn(II)位于反演中心,每个Mn(II)离子分别与两个配体中的羧基氧原子和四个水分子配位,形成了六配位的八面体构型。标题配合物中,在分子内和分子间氢键的共同作用下构筑了该化合物的三维氢键超分子网络结构。配合物的荧光光谱表明,与酮洛芬配体的荧光相比,形成配合物后,发生了荧光的猝灭。A new mononuclear Mn coordination complex [Mn2(C(16)H(13)O3)4(H2O)8]·2H2O was synthe- sized (C16H13O3 is ketoprofen anion), and characterized by elemental analysis, IR, PXRD, TG, lumi- nescence and X-ray single crystal diffraction. The complex[Mn2(C(16)H(13)O3)4(H2O)8]·2H2O belongs to trielinic system, space group P1,a =0. 867 42(4) nm, b =0. 897 47(3) nm, c =2. 194 13(9) nm, ct =92. 207(3) °,β =99. 615(4) °,γ= 108.738(3 )°, V = 1. 587 03 ( 11 ) nm^3, Z =4, R =0. 044 9. Each Mn(Ⅱ) cation lies on inversion center and is six -coordinated by two carboxyl oxygen atoms of two different ketoprofenate ligands and four water molecules, forming octahedral coordination geometry. A 3D supramoleeular network is formed by the interconnection of intramolecular and intermolecular hydrogen bonds. Luminescent spectrum demonstrates that the luminescence of the complex is quenched comparing to ketoprofenate ligand.
