英文摘要 | X-ray crystal structure and cryomagnetic properties of three organic radicals, 2-(2-pyridyl)- 4,4,5,5, etramethyl-4,5-dihydro-1-H-imidazol-1-oxy1-3-N-oxide (NIT-oPy) 1,2-(3-pyridyl)-4,4,5,5,- tetramethyl-4,5-dihydro-1-H-imidazol-1-oxyl-3-N-oxide (NIT-6M-oPy) 3 were investigated. The crystal structures of compounds 1-3 show the same feature of a P2 /c space group of a monoclinic system. Two crystal lographically independent molecules were found in the crystals of compounds 1-3. The temperature dependence of magnetic susceptibility of compounds 1-3 revealed an intermolecular antiferromagnetic exchange interaction. |
