Abstract
•A CuII coordination polymer [Cu(sbpc)(phen)(H2O)]⋅H2O was synthesized.•Sulfonate and carboxylate groups show varied coordination modes.•Weak antiferromagnetic exchange is available.
A CuII coordination polymer, [Cu(sbpc)(phen)(H2O)]⋅H2O 1, has been synthesized and characterized structurally and magnetically (H2sbpc = 4-sulfobiphenyl-4′-carboxylic acid, phen = 1,10-phenanthroline). Single-crystal structural analysis shows that 1 consists of dinuclear [Cu2(CO2)2] units bridged via sbpc2− to afford a 1-D chain, which then extends into the 3-D coordination polymer supramolecular network by O–H⋯O hydrogen bonds and π⋯π interactions. Magnetic measurements indicate that complex 1 exhibits weak antiferromagnetic coupling.
