FERROMAGNETIC BEHAVIOR OF TWO MANGANESE(II) COMPLEXES WITH PYRIDINE-SUBSTITUTED NITRONYL NITROXIDE RADICALS

摘要

Two compounds of formulae (Mn(dtbz)(2)(NITpPy)(2)(H2O)(2) (1) and Mn(tnp)(2)(NITpPy)(2)(H2O)2 . 3H(2)O (2), where dtbz=3,5-dinitrobenzoate, tnp=2,4,6-trinitrophenolate, NITpPy=2-(4-pyridal)-4,4,5,5-tetramethyl-4,5-dihydro-1H-imidazolyl 3-oxide, have been synthesized. Mn(dtbz)(2)(NITpPy)(2)(H2O)(2) (1) has been characterized by X-ray crystallography. It crystallizes in the triclinic space group P
