Abstract
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 finely determined by 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 µ3-OH group. The triangular sub-unit configuration supplied more stability during thermal decompositions.
Keywords: Coordination polymer, µ3-hydroxyl, tetrazole, triangular cluster.
