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 degrees. 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 degrees. 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 degrees.
