中文摘要	one mu-dichloro bridged diiridium complex and three mononuclear iridium(iii) complexes based on the 1,3,4-oxadiazole derivatives as cyclometalated ligands and acetylacetonate (acac) or dithiolates o,o'-diethyldithiophosphate (et(2)dtp) or n,n'-diethyldithiocarbamate (et(2)dtc) as ancillary ligands have been synthesized and systematically studied by x-ray diffraction analysis. the results reveal that three mononuclear complexes all adopt distorted octahedral coordination geometry around the iridium center by two chelating ligands with cis-c-c and trans-n-n dispositions, which have the same coordination mode as the diiridium dimer. the dinuclear complex crystallizes in the monoclinic system and space group c2/c, whereas three mononuclear iridium complexes are all triclinic system and space group p(1) over bar. in the stacking structure of the dimer, one-dimensional tape-like chains along the b-axis are formed by hydrogen bondings, which are strengthened by pi stacking interactions between phenyl rings of 1,3,4-oxadiazole ligands. then these chains assemble a three-dimensional alternating peak and valley fused wave-shape structure. in each stacking structure of three mononuclear complexes, two molecules form a dimer by the c-h center dot center dot center dot o hydrogen bondings, and these dimers are connected by pi stacking interactions along the b-axis, constructing a zigzag chain.
