| Abstract: | Four coordination polymers (CPs), [Cd(2,7-dpfo)2(NO3)2(CH3OH)]n (1) , [Zn(2,7-dpfo)(NO3)(CH3COO)]n (2) , [Co(2,7-dpfo)2(H2L)]n (3) , and [Ni(2,7-dpfo)2(H2L)]n (4) (where 2,7-dpfo is 2,7-di(pyridin-4-yl)-9H-fluoren-9-one and H4L 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. |
