Synthesis and crystal structures of two polymeric silver(I) complexes with polyamines and terephthalic acid

Two polymeric silver(I) complexes, [Ag(4)(TAA)(2)(TA)(2)] center dot 2[Ag(TA)(2)] (I) and [Ag(2)(TA)(BA)] (n) (II), where TAA is tris(2-aminoethyl)amine, TA is terephthalic acid, BA is butane-1,4-diamine, were synthesized and structurally characterized by elemental analyses and X-ray diffraction. Complex I consists of mononuclear [Ag(TA)(2)] units and TA-bridged tetranuclear [Ag(4)(TAA)(2)(TA)(2)] units, which are further linked via AgaEuro broken vertical bar Ag interactions to form chains. In complex II, the silver atoms are linked by the TA and BA groups to form chains, which are further linked via AgaEuro broken vertical bar Ag interactions to form layers. In both complexes, molecules are finally linked through intermolecular hydrogen bonds to form three-dimensional networks.
