A Zn(Ⅱ) complex with nitronyl nitroxide radicals [Zn(NIT3Py)2Cl2](1)(NIT3Py=2-(3’-pyridinyl)-4,4,5,5-tetramethylimidazoline-1-oxyl-3-oxide) has been synthesized and structurally characterized by X-ray diffraction crystal structure determination method.The complex has a mononuclear-metal structure in which each Zn(Ⅱ) ion adopts a distorted tetrahedral geometry and is coordinated by two Cl-anions and two pyridyl-N atoms from two NIT3Py radical ligands.The magnetic measurements show the weak antiferromagnetic interaction between the nitroxide radicals through the diamagnetic Zn(Ⅱ) ion.CCDC:292363.
