Coordination polymers of 1,8-bis(2-methylthioethoxy)anthraquinone and 1,5-bis(2-methylthioethoxy)anthraquinone with Ag(I): Synthesis and X-ray crystallography

► Coordination polymers of sulfur containing anthraquinone bipodant ligand with Ag(I). ► Rare examples of one-dimensional coordination polymers with sulfur donors. ► Coordination of intraannular carbonyl oxygen with metal ion is new in open bipodant. ► 3 showed an irreversible silver reduction at +0.28 V vs SCE in electrochemistry.
