Syntheses, Structures, and Properties of Transition Metal Complexes Constructed from 6-Methyl-2,3,5-pyridinetricarboxylic Acid

以6-甲基-2,3,5-吡啶三酸为配体和过渡金属盐反应,合成出2个新颖的金属配位聚合物{[Cu(Hmptc)(H2O)]·2H2O}n(1)和{Cd(Hmptc)(H2O)}n(2)(H3mptc=6-甲基-2,3,5-吡啶三酸)。配合物1存在具有四边形孔道的二维网状结构。配合物2中的Cd(Ⅱ)中心通过Hmptc2-配体连接成为类似于笼状的二维层状结构,进一步由氢键相互作用连接成三维超分子结构。配合物2存在蓝绿色荧光。

Two new transition metal coordination polymers, {[Cu（Hmptc）（HEO）]· 2H2O}, （1） and {Cd（Hmptc）（H2O）}, （2）, were successfully constructed from transition metal salts with 6-methyl-2,3,5-pyridinetricarboxylic acid （H3mptc）. Complex 1 exhibits a 2D coordination network, in which rectangle channels are shown to exist. In complex 2, Cd（Ⅱ） centers are linked by Hmptc2- ligands into 2D grid-like layers, which are further linked by hydrogen bonding interactions to form a 3D supramolecular network. In addition, complex 2 exhibits blue/green luminescence in the solid state at room temperature. CCDC： 906071, 1; 906072, 2.
