Two coordination polymers, [Co 2 (Hcpip) 2 (phth)] n · 3 n (H 2 O) ( 1 ) and [Mn 2 (Hcpip) 2 (phth)] n ( 2 ), {H 2 cpip = 2‐(2‐carboxyphenyl)imidazo[4,5‐f](1,10)‐ phenanthroline, H 2 phth = phthalic acid}, were hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, and single‐crystal X‐ray diffraction. Complex 1 is a 1D chain, in which the dinuclear [Co 2 (Hcpip) 2 ] 2+ units are linked through (phth) 2– anions. Complex 2 is a 2D layer structure, which is constructed from the 1D chains bridged by (phth) 2– anions. The magnetic properties of 1 and 2 show that the weak ferromagnetic interactions occurred between Co II ions in 1 and a weak antiferromagnetic interactions exist between Mn II ions in 2 . These two complexes have good thermal stabilities.
