Abstract

A novel [Ag-2(mu-sac)(2)(mu-hep)(2)](n) [sac=saccharinate and hep={N-(2-hydroxyethyl)piperazine}] was synthesized and characterized. [Ag-2(mu-sac)(2)(mu-hep)(2)](n) consists of dimeric [Ag-2(mu-sac)(2)] units bridged by the hep ligands, resulting a one-dimensional coordination polymer. [Ag-2(mu-sac)(2)(mu-hep)(2)](n) contains two different silver(I) centerswith a Ag-Ag separation of 3.492(2) A. One of the silver(I) ion is trigonal planar to the imino N and carbonyl O atoms of two sac ligands and one of the N atom of hep, while the other silver(l) ion is tetrahedrally coordinated by the N and carbonyl O atoms of two sac ligands and the N and O chelating hep ligand.
