摘 要: | A novel diamagnetic-metal Cd(Ⅱ) complex with four nitroxide radicals[Cd(IM4Py)4Cl2](IM4Py=2-(4'-pyridinyl)-4,4,5,5-tetramethylimidazoline-1-oxyl) was synthesized and characterized by elemental analyses,IR spectra,UV-Vis spectra and X-ray single crystal diffraction.The complex crystallized in triclinic space group P1 with a=0.93285(14) nm,b=1.16827(18) nm,c=1.3660(2) nm,α=112.759(2)°,β=104.524(2)°,γ=92.008(3)°,V= 1.3143(3) nm3,Z=1,Dc=1.335 g/cm3,the final R1=0.0423 and wR2=0.1009.In the title complex,each Cd(Ⅱ) ion adopting a distorted octahedral geometry is coordinated by two Cl-anions and four pyridyl-N atoms from four IM4Py ligands.The magnetic measurements show the weak antiferromagnetic interactions between the nitroxide radicals.
