Abstract

Three new silver(I) phosphonate complexes have been synthesized from silver phenylethynide as a structure-directing precursor. Ag2(PhPO3)(H2O) displays a layer-type coordination network, Ag(3,5-dimethylpyrazole)2(PhPO3H) contains a dimeric unit, and {Ag8(dppm)4((t)BuPO3)2(ClO4)(NO3)(0.67)(H2O)(1.33)}·(ClO4)(2.33)·(CH3OH)(6.67) features an octanuclear composite cluster. We have also isolated the pyrophenylphosphonate complex Ag2[PhPO2(O)O2PPh](CH3CN), which exhibits an infinite-chain structure.
