Two complexes, namely [Mn 3 (hpda) 2 (H 2 O) 8 ] n ( 1 ) and [Co 3 (hpdaH) 3 (H 2 O) 7 ] · (4, 4′py) · (H 2 O) 3 ( 2 ) (hpdaH 3 = 4‐hydroxypyridine‐2, 6‐dicarboxylic acid) were synthesized under hydrothermal conditions and were characterized by elemental analysis, IR spectrocopy, and X‐ray diffraction. Complex 1 forms a 1D linear chain, which is extended by hydrogen bonds resulting in a 3D network. Complex 2 consists of a trinuclear cobalt(II) unit, which is further linked by hydrogen bonds to form a 3D supramolecular network. Magnetic measurements show that there is a weak antiferromagnetic interaction between the adjacent Mn II ions in 1 .
