Two Cu II complexes [Cu 3 (2,2′‐bipy) 2 (pdc) 2 )(H 2 O) 2 ] · 2H 2 O ( 1 ) and [Cu 4 (2,2′‐bipy) 2 (pdc) 2 (OH) 2 ] n · 2 n H 2 O ( 2 ) (2,2′‐bipy = 2,2′‐bipyridine; H 3 pdc = 3,5‐pyrazoledicarboxylic acid) were synthesized under hydrothermal reaction conditions. Because of different experimental conditions, the structure of complex 1 is built up of a trinuclear Cu II unit and solvate water molecules, whereas complex 2 has an novel one‐dimensional coordination polymeric structure linked by three kinds of bridging groups in an alternating manner. Magnetic susceptibility measurements of the compounds were performed and indicated antiferromagnetic interactions in 1 and ferromagnetic interactions in 2 .
