Synthesis,crystal structure and ferromagnetic interactions of a silver(I) complex with imizadolyl-substituted nitroxide radicals |
| |
Abstract: | A silver(I) complex with nitronyl nitroxide, [Ag2(NIT-R)4(NO3)2]?·?CH3OH [NIT-R?=?2-(5-methylimidazol-4-yl)-4,4,5,5-tetramethyl-2-imidazoline-1-oxyl-3-oxide], has been prepared and characterized by magnetic and single-crystal X-ray diffraction studies. In the complex, the silver(I) ion is coordinated with two monodentate nitronyl nitroxide radicals by the nitrogen of the imizadole ring. The silver(I) ion is two-coordinate and forms a dimer through Ag?···?Ag weak metal bonding interactions. The magnetic properties for the title complex have been investigated in the temperature range 2?~?300?K showing ferromagnetic interactions between the coordinated nitronyl nitroxides (J?=?3.64?cm?1) and intermolecular antiferromagnetic interactions. |
