Synthesis, Crystal Structure, and Electrochemical Property of the Complex [Co(tfbdc)(DMF)₂(H₂O)₂] (tfbdc = Tetrafluoroterephthalate; DMF = N,N-Dimethylformamide)

摘要

One complex [Co(tfbdc)(DMF)₂(H₂O)₂] (tfbdc = tetrafluoroterephthalate) was synthesized by the reaction of tetrafluoroterephthalatic acid with cobalt(II) nitrate hexahydrate in mixture solvent. This complex was characterized by elemental analysis, infrared (IR) spectra, cyclic voltammetry, and x-ray single-crystal structure analysis. This complex crystallizes in the monoclinic system with space group P2(1). The Co(II) ion has a distorted octahedral geometry coordinated by two O atoms from two tetrafluoroterephthalate (tfbdc), two O atoms from two water molecules, and two O atoms from two N,N-dimethyl formamide molecules. Each tfbdc ligand bridges two Co(II) ions in end-to-end fashion, forming a straight chain. These chains are connected by hydrogen bonds, forming a two-dimensional supramolecular network structure.View full textDownload full textKeywordscobalt(II), coordination polymer, crystal structure, electrochemical property, tetrafluoroterephthalatic acidRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/15533174.2011.609208
