This work reports the ambient temperature synthesis and structural characterisation of six new first row transition metal acetylenedicarboxylate coordination polymers. The Co and two Ni compounds adopt structures in which the octahedral metals are connected into 1D chains via the acetylenedicarboxylate ligand. In contrast the Mn and two Zn compounds adopt 3D metal-organic frameworks; while the Mn compound is non-porous the two Zn structures contain dimeric or trimeric clusters connected into frameworks that are potentially porous. These two anionic metal-organic frameworks are, however, charged balanced by cations siting in their pores which greatly reduces the ability to access their porosity.

六种过渡金属乙炔二羧酸配位聚合物的常温合成及结构表征

这项工作报告了六种新的第一行过渡金属乙炔二羧酸配位聚合物的环境温度合成和结构表征。Co 和两种 Ni 化​​合物采用八面体金属通过乙炔二羧酸盐配体连接成一维链的结构。相比之下，Mn 和两种 Zn 化合物采用 3D 金属有机骨架；虽然 Mn 化合物是无孔的，但两个 Zn 结构包含连接成潜在多孔骨架的二聚体或三聚体簇。然而，这两种阴离子金属-有机骨架通过位于其孔隙中的阳离子电荷平衡，这大大降低了进入其孔隙率的能力。
