摘要

Three coordination polymers, {[Zn(L)(2)] center dot H2O)(n) (1), {[Cd(L)(2)]center dot H2O}(n) (2) and {[Mn(L)2]center dot H2O), (3) (HL = 2hydroxy-N-1H-tetrazol-5-ylbenzamide), have been prepared under hydrothermal conditions. X-ray diffraction analysis reveals that compounds 1-3 are isomorphous, showing an interdigitated 3-D framework with 1-D channels. Fluorescence studies show that the emissions of complexes 1-2 are attributed to the ligand pi-pi* transition. Magnetic studies indicate that compound 3 exhibits antiferromagnetic properties.
