Abstract：

Three　new　cluster-based　CuIIazide　coordination　polymers,　[Cu8(N3)16(222-tet)2]n　(1),　[Cu10(N3)20(dien)2]n　(2),　and　[Cu12(N3)24(Me5dien)　2]n　(3)　as　well　as　a　1D　polymer　[Cu2(N　3)4-　(dien)]n,　(4)　were　prepared　by　hydrothermal　reactions　of　CuII　ions　with　NaN3　in　the　presence　of　various　polyamines.　Single-crystal　X-ray　diffraction　studies　reveal　that　1　has　a　ID　chain　structure　based　on　an　octanuclear　cluster　unit　(Cu　8　(N3J16-　(222-tet)2}.　Complexes　2　and.　3　are　3D　polymers　and　in　both　cases　the　azido　anions　display　five　different　bridging　modes　(μ-1,　1,　μ-1,　3,　μ-1,　1,　1,　uμ-l,　l,　3,　uμ　-l,　l,　l,　3).　Compound　4　is　a　ID　chain　that　represents　the　first　example　of　a　Cu　II-azide　compound　that　contains　cis-EE,　double　EO,　and　terminally　bonded　azido　ligands.　The　magnetic　susceptibility　data,　measured　from　2　to　300　K,　showed　ferromagnetic　couplings　in　1,　2,　and　4　and　antiferromagnetic　interaction　in　3.　The　magnetic　data　of　1　and　4　were　fitted　with　rough　models,　giving　the　exchange　coupling　constants　J　=　4.1.9　cm-1　for　1　and　J=25.31Cm-1　for　4.　©　2010　Wiley-VCH　Verlag　GmbH　&　Co.　KGaA.
