Two coordination polymers, namely {[Mn2(HL)2(bpe)(H2O)8]·5H2O}n (1) and {[Ni3(L)2(bpe)3(H2O)6]·3H2O}n (2) (H3L = 1,3,5-tris(carboxymethoxy)benzene, bpe = 1,2-bis(4-pyridyl)ethylene), have been hydrothermally synthesized. In compound 1, two Mn2+ ions are linked by two HL2− ligands into rings. Adjacent rings are linked through hydrogen bonding between carboxylic groups and water molecules to produce a three-dimensional supramolecular network, which shows channels along the b axis that are occupied by the free bpe molecules. Compound 2 possesses a 3D architecture, constructed from Ni-bpe chains and L3− linkers. The 3D architecture is further consolidated by the hydrogen-bonding interactions. The magnetic properties of complexes 1 and 2 have been investigated. Antiferromagnetic interactions were observed for complexes 1 and 2.
