| 英文摘要 | Four new mononuclear Fe(III) complexes 1-4 of 2-methyl-6-(pyrimidin-2-yl-hydrazonomethyl)-phenol (H2L) have been synthesized and characterized by magnetic susceptibility measurements and single-crystal X-ray diffraction analysis. Complexes 1-3 are ionic compounds with the formula [Fe(HL)(2)] X-nsolvent (X = ClO4- (1), BF4- (2) and Cl- (3)), while complex 4 ([Fe(HL)(L)]) is neutral. The central Fe(III) ion in complexes 1-4 is coordinated by four nitrogen and two oxygen atoms of two Schiff base ligands HL- or L2-, and the coordination geometries of Fe-III are all distorted octahedral. Magnetic measurements indicate that complex 1 shows an abrupt spin transition with a thermal hysteresis of 32 K (T-1/2 down arrow = 158 K and T-1/2 up arrow = 190 K), and complex 4 exhibits a gradual incomplete spin transition. Complexes 2 and 3 are high spin with a room-temperature T-chi m value of 4.32 cm(3) K mol(-1) and 4.39 cm(3) K mol(-1), respectively. |
