Four Coordination Polymers Constructed from 3, 5‐Bis‐oxyacetate‐benzoic Acid and N‐donor Ligands

Four coordination polymers, [ M 3 (boaba) 2 (4, 4′‐bipy) 2 (H 2 O) 8 ] [ M = Co ( 1 ), Ni ( 2 ), Mn ( 3 )] and [Cu 3 (boaba) 2 (bimb) 3 ] · 4H 2 O ( 4 ) [H 3 boaba = 3, 5‐bis‐oxyacetate‐benzoic acid, 4, 4′‐bipy = 4, 4′‐bipyridine, bimb = 1, 4‐bis(imidazol‐1′‐yl)butane], were hydrothermally synthesized and characterized by single‐crystal X‐ray diffraction, IR spectroscopy, and TG analyses. Compounds 1 – 3 are isostructural and crystallize in the triclinic P $\bar{1}$ space group. Their structures can be considered constructed from two‐dimensional layers, which consist of two neighboring 1D ladder chains and are further linked by intermolecular O–H ··· O hydrogen bonds into a 3D supramolecular network. Compound 4 is a 3D (3, 4, 4)‐connected topology network.
