Four-and Three-Fold Interpenetrated(3,4)-Connected d10 Metal Coordination Polymers Constructed by 3,5-Bis(pyridin-4-ylmethoxy)benzoic Acid and Aromatic Dicarboxylic Acid Ligands
【摘要】 以3,5-二(吡啶-4-甲氧基)苯甲酸(HL)与芳香二羧酸为配体,在水热条件下与Zn(Ⅱ)或Cd(Ⅱ)盐反应得到4个具有3,4-连接多重穿插结构的配位聚合物:[Zn2L2(tdc)]n(1),{[Zn4L4(Hhdc)2]·H2O}n(2),{[Zn2L2(Hhdc)]·H2O}n(3),{[Cd2L2(bdtc)(H2O)]·0.5H2O}n(4)(H2tdc=2,5-噻吩二甲酸,H3hdc=5-羟基间苯二甲酸,H2bdtc=1,4-苯二硫乙酸)。晶体结构分析表明,聚合物13具有3,4-连接四重穿插的三维网络结构,拓扑符号分别为(4.82)(4.85)(1)、(63)(65.8)(2)和(63)(65.8)(3)。4为3,4-连接三重穿插的二维平面结构,拓扑符号为(63)(66)。测定了配位聚合物1、3和4的热稳定性和荧光性质。
【Abstract】 The reaction of 3,5-bis(pyridin-4-ylmethoxy)benzoic acid(HL) and a combination of dicarboxylic acid ligands such as thiophene-2,5-dicarboxylic acid(H2tdc), 5-hydroxybenzene-1,3-dicarboxylic acid(H3hdc), 1,4-benzenedithioacetic acid(H2bdtc) with Zn (Ⅱ) and Cd(Ⅱ) metal ions give rise to four coordination polymers with interpenetrating(3,4)-connected networks, namely, [Zn2L2(tdc)]n(1), {[Zn4L4(Hhdc)2]·H2O}n(2), {[Zn2L2(Hhdc)]·H2O}n(3), {[Cd2L2(bdtc)(H2O)]·0.5H2O}n(4). 13 exhibit(3,4)-connected 4-fold-interpenetrating 3D networks with point symbol of(4.82)(4.85)(1),(63)(65.8)(2) and(63)(65.8)(3) topology, respectively. 4 displays a(3,4)-connected3-fold-interpenetrating 2D network with(63)(66) topology. Luminescent properties of 1, 3 and 4 were also investigated. CCDC: 852424, 1; 872035, 2; 887738, 3; 872037, 4.
