摘　　要：A novel one-dimensional (1D) Cu(Ⅱ) nitronyl nitroxide complex bridged by iminodiacetate dianion [Cu(NIT4Py)(IDA)]n,where NIT4Py=2-(4'-pyridyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide and IDA= iminodiacetate dianion,was synthesized and structurally characterized by X-ray diffraction. It crystallizes in monoclinic,space group P21/c with a=0.921 09(10) nm,b=0.780 09(9) nm,c=2.486 3(3) nm,β=96.826(2)°. The Cu(Ⅱ) ion is five-coordinated with a distorted square-pyramidal geometry. Each iminodiacetate dianion bridges two Cu(Ⅱ) ions via a monodentate-tridentate mode into a 1D chain,and these 1D chains are further linked into a 2D network via hydrogen-bonding interactions.A novel one-dimensional （1D） Cu（Ⅱ） nitronyl nitroxide complex bridged by iminodiacetate dianion [Cu（NIT4Py）（IDA）]n,where NIT4Py=2-（4＇-pyridyl）-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide and IDA= iminodiacetate dianion,was synthesized and structurally characterized by X-ray diffraction.
