CRYSTAL STRUCTURES OF TWO ONE-DIMENSIONAL COORDINATION POLYMERS CONSTRUCTED FROM Mn~(2+) IONS, CHELATING HEXAFLUORO-ACETYLACETONATE ANIONS, AND FLEXIBLE BIPYRIDYL BRIDGING LIGANDS

摘要

The syntheses and crystal structures of two one-dimensional coordination polymers, [Mn(C5HO2F6)2(C16H2ON2)]_n (1) and [Mn(C5HO2F6)2(C_(20)H2ON2)]_n (2), are described, where C5HO2F6" is the hexafluoro acetylacetonate anion, C_(16)H2ON2 is l,6-bis(4-pyridyl)-hexane, and C_(20)H_(20)N2 is 1,4-bis[2-(3-pyridyl)ethyl]-benzene. In both phases, the metal ion lies on a crys-tallographic twofold axis and is coordinated by two chelating C5HO2F6~- anions and two bridging bipyridyl ligands to generate a cis-MnN2O4 octahedron.
