Three Coordination Polymers Sustained by Triangularly Secondary Building Units with Trinuclear Centers: Self-assembly and Structural Characterization
Justyna M. Zurek, Shao Xiong Xie, Sheng Hu and Yan Yan
Three coordination polymers with triangularly secondary building units based on trinuclear metal centers and three tetrazolyl ligands were successfully assembled, and their crystal structures were well determined through single-crystal X-ray diffraction method. Crystallographic analysis indicated that in every triangular sub-construction unit, three metal ions (Co2+ or Cd2+) adopted an octahedral coordination model to be linked together by three tetrazolyl ligands and one 3-OH group. The triangular sub-unit configuration supplied more stability during thermal decompositions.
