Chelating, bridging, and chain structures within Ag(I) and Cu(I) complexes of bis(nicotinyloxy), bis(isonicotinyloxy), and bis(pyrimidine-5-carboxyloxy)-1,8-disubstituted anthraquinone ligands

Bis-substituted anthraquinone ligands containing nitrogen heterocycles form both chelating and bridging complexes with Ag(I) and Cu(I), as well as two new coordination polymers.
