  ) and [Zn 2 (Hpta) 2 (H 2 O) 6 ]·4H 2 O ( 2 ) are mononuclear and binuclear structures, respectively; while [Ag(H 2 pta)(H 2 O)] n ( 3 ) is a helical 1D chain coordination polymer. A double chain was further formed in 3 by the weak interaction between oxygen atoms and Ag(I) ions. Through hydrogen bonds the three complexes constructed corresponding 3D network structures. The three complexes were characterized
