Abstract

Abstract : Four coordination polymers (CPs), [Cd(2, 7‐dpfo)2 (NO3 )2 (CH3 OH)] n (1), [Zn(2, 7‐dpfo)(NO3 )(CH3 COO)] n (2), [Co(2, 7‐dpfo)2 (H2 L)] n (3), and [Ni(2, 7‐dpfo)2 (H2 L)] n (4) (where 2, 7‐dpfo is 2, 7‐di(pyridin‐4‐yl)‐9 H ‐fluoren‐9‐one and H4 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. Abstract : Four coordination polymers based on Cd 2+ /Zn 2+ /Co 2+ /Ni 2+ and 2, 7‐di(pyridin‐4‐yl)‐9 H ‐fluoren‐9‐one were obtained. All four coordination polymers display one‐dimensional chain structures. The solid‐state luminescent properties of 1 and 2 and the magnetic properties of 3 and 4 were also investigated.
