Chiral azide-bridged two-dimensional Cu(II) compounds showing a field-induced spin-flop transition

Two azide-bridged chiral Cu(II) compounds, [Cu(R,R-dacy)(N3)2]n(1)(R,R-dacy =trans-(1R,2R)-diaminocyclohexane) and [Cu(S,S-dacy) (N3)2]n(2)(S,S-dacy =trans-(1S,2S)-diaminocyclohexane), with two-dimensional layer structures exhibiting end-to-end and end-on azide bridging patterns, were prepared and among them 1 was examined to show a field-induced spin-flop transition.
