nitronyl nitroxide radical%iminodiacetic acid%copper(Ⅱ) complex%crystal structure
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. CCDC: 773132.
