Solvothermal synthesis and characterization of coordination polymers of cobalt(II) and zinc(II) with succinic acid

The complexes [Co(C 4H 4O 4)] n (1) and [Zn(im)2- (C 4H 4O 4)] n (2) (C 4H 4O 4 = succinate dianion, suc; im = imidazole) have been synthesized solvothermally and characterized by elemental analysis, IR, TG-DTA, and single-crystal X-ray diffraction techniques. Complex 1 is the first anhydrous member of the cobalt succinate family and has high thermal stability under a static air atmosphere, up to 425 °C, and complex 2 is a 1D coordination polymer. In addition, a new synthesis method and some properties of the known [Co(HCOO) 2.2H 2O] n (3) complex are reported. After in situ synthesis of 3 via decomposition of DMF at 140 °C, it was found that complex 3 can adsorb some solvents repeatedly and is selective for H 2O. © Springer Science+Business Media B.V. 2012.Yükseköğretim Kurulu Atatürk Üniversitesi 2010.102.02.2 American Research Institute in TurkeyAcknowledgments This work was financially supported by Rize University (No. 2010.102.02.2).
