Four new transition metal complexes: [Cu(Hcppa) 2 (H 2 O) 2 ] ( 1 ), [Co 2 (cppa) 2 (H 2 O) 10 ] ( 2 ), [Co 3 (cpia) 2 (H 2 O) 8 ] · 2H 2 O ( 3 ) and [Ni 3 (cpia) 2 (H 2 O) 12 ] · 6H 2 O ( 4 ) {H 2 cppa = 3‐(4‐(carboxymethoxy)phenyl]propanoic acid; H 3 cpia = N ‐[4‐(carboxymethoxy)phenyl]iminodiacetic acid} were synthesized and characterized. Complexes 1 and 2 show mononuclear structures, complexes 3 and 4 exhibit dinuclear structures. All complexes extend to 3D supramolecular networks through hydrogen bonds, of which complexes 3 and 4 display microporous structures. In complexes 2 – 4 the water clusters are trapped by the cooperative association of coordinate interactions as well as hydrogen bonds, forming different 1D metal‐water chain structures. Thermal stabilities of complexes 1 – 4 were discussed.
