摘要：
The heating of a mixture of as-precipitated scandium hydroxide and tetrafluoroterephthalic acid in ethylene glycol leads to the formation of the complex [Sc-2(HOCH2CH2OH)(4)(tFBDC)(3)]2HOCH(2)CH(2)OH (tFBDC(2-) = tetrafluoroterephthalate) (1). According to the X-ray data, compound 1 is a chain coordination polymer. Sc(III) cations and tFBDC(2-) anions form double chains (ribbons). The coordination number of Sc(III) is completed to seven by ethylene glycol molecules acting as chelate ligands. There is a complex system of hydrogen bonding interactions induced by oxygen atoms of carboxylic groups of perfluorinated ligands and coordinated and lattice ethylene glycol.
