Abstract. The 3D cobalt(II) coordination polymers [Co 1.5 (HDDB)(1,4‐bib) 1.5 (H 2 O)] n ( 1 ), and {[Co 2 (DDB)(1,3‐bib) 2 (μ 2 ‐H 2 O)] · H 2 O} n ( 2 ) were assembled by mixed‐ligand synthetic strategy [H 4 DDB = 1,3‐bis(2,4‐dicarboxyphenyl) benzene, 1,3‐bib = 1,3‐bis(1H‐imidazol‐4‐yl)benzene, and 1,4‐bib = 1,4‐bis(1H‐imidazol‐4‐yl)benzene]. Their structures were determined by single‐crystal X‐ray diffraction analyses and further characterized by elemental analyses (EA), IR spectroscopy, powder X‐ray diffraction (PXRD), and thermogravimetric (TG) analyses. Single X‐ray diffraction analysis reveals that complex 1 is an interestingly 3D (3,3.6)‐connected (6 3 ) 4 (6 5 · 8 8 · 10 2 ) net, and complex 2 is an unprecedented dinuclear [Co 2 (COO)(μ 2 ‐H 2 O)] SBUs based 3D (3,6)‐connected (3 · 6 · 7)(3 2 · 4 3 · 5 4 · 6 3 · 7 · 8 2 ) net. Additionally, the magnetic properties of 2 were investigated.
