Solvothermal Synthesis, Crystal Structure and Luminescence Property of a 1D Silver(Ⅰ) Coordination Polymer

An unprecedented one-dimensional coordination polymer [Ag2(PhP O3 H)2(DPPP)]n(1) based on phenylphosphonic acid(Ph PO3 H2) and 1,3-bis(diphenyphosphino)propane(DPPP) has been synthesized and characterized by IR, elemental analyses, thermogravimetric analyses and X-ray diffraction technique. Single-crystal-X-ray diffraction analyses revealed that the complex crystallizes in triclinic system, space group P(16). The coordination geometry of each Ag(I) ion is planar trigonal. Two kinds of rings were found in 1, such as the four-membered ring with Ag2 O2 and the eight-membered ring with Ag2 O4 P2 constructed by PhP O3 H- ligands, which were then connected by DPPP ligands forming a zigzag type chain. Moreover, the light absorption and luminescent property of 1 were also investigated.
