Four coordination polymers (CPs), [Cd(2,7‐dpfo) 2 (NO 3 ) 2 (CH 3 OH)] n (1) , [Zn(2,7‐dpfo)(NO 3 )(CH 3 COO)] n (2) , [Co(2,7‐dpfo) 2 (H 2 L)] n (3) , and [Ni(2,7‐dpfo) 2 (H 2 L)] n (4) (where 2,7‐dpfo is 2,7‐di(pyridin‐4‐yl)‐9 H ‐fluoren‐9‐one and H 4 L is 1,1′:4′,1′′‐terphenyl‐4,2′,5′,4′′‐tetracarboxylic acid), were synthesized and structurally characterized. Compounds 1 – 4 were determined by elemental analyses, single crystal X‐ray diffraction analyses, powder X‐ray diffraction, infrared spectroscopy, and thermogravimetric analyses. Compound 1 displays a one‐dimensional (1D) zigzag chain structure, while compound 2 possesses a 1D ladder chain structure. Compounds 3 and 4 are isostructural and consist of 1D chains. The solid‐state luminescent properties of 1 and 2 and the magnetic properties of 3 and 4 were also investigated.
