Their structures have been determined by single-crystal X-ray diffraction analyses and further characterized by elemental analyses（EA）, powder X-ray diffraction（PXRD）, and thermogravimetric（TG） analyses. Single-crystal X-ray diffraction analysis reveals that the crystals of complexes 1~3 are all in triclinic systems, space group P1. Complexes 1 and 2 are 0D binuclear structures, and 3 is a 1 D chain. Moreover, the solid state fluorescence properties of 1 and 2 have been investigated.展开更多
