摘要
通过水热方法获得了2个镍配合物:[Ni(3,3′-dpdc)(dpp)]n(1),[Ni(2,2′-dpdc)(phen)(H2O)2]n(2)(3,3′-H2dpdc=3,3′-联苯二甲酸,2,2′-H2dpdc=2,2′-联苯二甲酸、phen=菲咯啉,dpp=1,3-二(4-吡啶基)丙烷),通过X射线单晶衍射的方法测定了其晶体结构。配合物1为二维网格型结构,中心金属离子为扭曲的[NiO4N2]八面体构型,3,3′-dpdc配体的2个羧基采取双齿螯合的配位模式与Ni髤离子配位形成Ni-(3,3′-dpdc)一维链结构,dpp配体采取单氮原子桥连的配位模式连接2个Ni髤离子形成Ni-dpp一维链,两种链相互贯穿形成二维网格型结构,二维网格结构之间通过氢键C15D-H15…O2、C21-H21A…O1形成三维超分子结构。配合物2为一维之字链结构,中心金属离子为扭曲的[NiO_4N_2]八面体构型,2,2′-dpdc的2个羧基均采取单齿桥连配位模式连接2个Ni髤离子形成一维之字型链结构,一维链之间通过O-H…O和C-H…π弱作用力连接形成三维超分子结构。探究了2种配合物对有机染料罗丹明B的光催化降解性能,结果表明配合物可以高效地降解罗丹明B。
Two complexes [Ni(3,3′-dpdc)(dpp)]n(1) and [Ni(2,2′-dpdc)(phen)(H_2O)_2]n(2) were obtained under different reaction conditions(2,2′-H2 dpdc=2,2′-biphenyldicarboxylic acid, 3,3′-H2 dpdc=3,3′-biphenyldicarboxylic acid, phen=1,10-phenanthroline, dpp=1,3-bis(4-pyridyl)propane), and their structures were characterized by X-ray single crystal diffraction. Complex 1 belongs to monoclinic system, space group P21/c. It has two-dimensional grid structure and the coordination environment of Ni (Ⅱ) ion is [NiO_2N_4]. The two carboxyl groups of the 3,3′-dpdc ligand coordinate to the Ni (Ⅱ) ion by a bidentate chelate coordination mode to form a Ni-(3,3′-dpdc) onedimensional chain structure, and the dpp ligand adopts a single nitrogen atom bridged coordination mode to connect two Ni(Ⅱ)) ions to form a Ni-dpp one-dimensional chain. The two chains penetrate each other to form a two-dimensional grid structure. The two-dimensional grid structure is stacked into a three-dimensional structure by C15D-H15…O2, C21-H21 A … O1 hydrogen bonding. Complex 2 belongs to orthorhombic crystal system,space group P212121. The complex shows a one-dimensional zigzag structure. The coordination envrionment of Ni(Ⅱ) ion is [NiO4 N2]. The two carboxyl groups of 2,2′-dpdc adopt a single-tooth bridged coordination mode. The adjacent Ni(Ⅱ) ions are linked by 2,2′-dpdc ligand to form the Ni-2,2′-dpdc zigzag chain structure, and the chains are connected to form a three-dimensional supramolecular structure by O-H…O and C-H…π. The photocatalytic degradation of the organic dye rhodamine B by two complexes was investigated. The results show that complexes can degrade rhodamine B efficiently.
