One-dimensional structures of manganese(II), copper(II) and cobalt(II) coordination complexes [Mn(II)(hfac)2L] (hfac = hexafluoroacetylacetonate anion; L = 4,4-bipyridyl), [Cu(II)(hfac)2L] (L = 1,3-dipyridylpropane or 4,4-bipyridyl-N,N'-dioxide) and [Co(II)(hfac)2L] (L = 4,4-bipyridyl-N,N'-dioxide)

Abstract

Treatment of bis(hexafluoroacetylacetonato)diaquamanganese(II) [Mn(hfac)2(H2O)2] with 4,4-bipyridyl gives cis-[Mn(II)(hfac)2-(bipy)] (1), which forms zig-zag 1-D chains. The bipyridyl ligands coordinate to the Mn cations adopting a cis geometry with an N-Mn-N angle of 90°. Treatment of bis(hexafluoroacetylacetonato)diaquacopper(II) [Cu(hfac)2(H2O)2] with 1,3-dipyridylpropane gives trans-[Cu(II)(hfac)2(1,3-dipy)] (2), which forms 1-D chains that adopt a trans N-Cu-N angle of 180°. Treatment of [M(hfac)2(H2O)2] (M = Co or Cu) with 4,4-bipyridyl-N,N'-dioxide gives trans-[Co(II)(hfac)2(4,4-bipy-N,N'-dioxide)] (3) and trans-[Cu(II)(hfac)2(4,4-bipy-N,N'-dioxide)] (4), respectively, which form isostructural linear chains with an O-M-O angle of 180°.
