| Abstract: | Four new transition metal complexes: Cu(Hcppa)2(H2O)2] ( 1 ), Co2(cppa)2(H2O)10] ( 2 ), Co3(cpia)2(H2O)8] · 2H2O ( 3 ) and Ni3(cpia)2(H2O)12] · 6H2O ( 4 ) {H2cppa = 3‐(4‐(carboxymethoxy)phenyl]propanoic acid; H3cpia = 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. |
