摘要
3,5-二羧酸吡啶(3,5-H2pydc)和四水氯化锰或六水氯化钴在水热条件反应得到了两个二维层状结构的配位聚合物[M(3,5-pydc)(H2O)2]n(M=Mn1,Co2),呈中性的金属-有机骨架结构是由三齿的3,5-pydc结构单元和水合金属离子构成的。这两个配合物中的中心金属离子都是平面双锥体配位几何:配合物1为五角双锥,而配合物2为三角双锥。
The hydrothermal reactions between 3,5-pyridinedicarboxylic acid (3,5-H2pydc) and MCl2·nH2O (M=Mn, Co;n=4,6) afforded coordination polymeric complexes [M(3,5-pydc)(H2O)2], (M=Mn 1, Co 2) with two-dimensional (2D) layer structures. The neutral metal-organic framework has been constructed from tri--connected building blocks 3,5- pydc and metal-aquo species. The metal centers in two complexes are the square pyramidal coordination geometries: pentagonal bipyamidal and trigonal bipyamidal for 1 and 2, respectively.
