Hydrothermal reactions of d(10) metal ions (Cd(2+) and Zn(2+)) with 1,4-naphthalenedicarboxylate acid (1,4-H2NDC) and 4,4'-dipyridyl N,N'-dioxide (4,4'-dpdo) form two three-dimensional grid-like coordination polymers [Cd2(1,4-NDC)2(4,4'-dpdo)]·H2O 1 and Zn4(μ3-OH)2(1,4-NDC)3(H2O)2·2H2O 2. Both coordination polymers were characterized by single crystal X-ray diffraction, IR spectroscopy, XRPD, thermogravimetric and elemental analyses. Polymer 1 exhibits rare alternating arranged 1,4-NDC(2)(-) and 4,4'-dpdo spacers between adjacent 1D zigzag chains containing Cd-octahedral coordination geometries. Polymer 2 is constructed from infrequent chair-like Zn4(μ3-OH)2 inorganic SBUs with four- and six-coordination geometries and only 1,4-NDC(2)(-) as "single-bridge" and "double-bridges" to form a 3D framework. Both polymers give strong luminescent emissions in the solid state at room temperature.
水热反应 d(10) 金属离子（Cd(2+) 和 Zn(2+)）与 1,4-萘二甲酸酸（1,4-H2NDC）和 4,4'-联吡啶 N,N'-二氧化物（4,4'-dpdo）形成两个三维网格状配位聚合物 [Cd2(1,4-NDC)2(4,4'-dpdo)]·H2O 1 和 Zn4(μ3-OH)2(1,4-NDC)3(H2O)2·2H2O 2。这两种配位聚合物都通过单晶 X 射线衍射、红外光谱、XRPD、热重分析和元素分析进行了表征。聚合物 1 表现出罕见的交替排列的 1,4-NDC(2)(-) 和 4,4'-dpdo 间隔物，位于相邻的 1D 之字形链之间，其中包含 Cd-八面体配位几何形状。聚合物 2 由罕见的椅式 Zn4(μ3-OH)2无机 SBUs 构建而成，具有四配位和六配位几何形状，仅使用 1,4-NDC(2)(-) 作为“单桥”和“双桥”，形成 3D 框架。两种聚合物在室温下的固态中都具有强烈的发光发射。
