摘要：

Reaction of the N,N,O-terdentate ligand 2-(2-hydroxyphenyl)-1,10-phenanthroline (HL) with Mn(CH3CO2)2.4H2O and NaClO4 affords [Mn(II)4L6][ClO4]2; X-ray analysis reveals a chain of four Mn(II) centers, with each adjacent pair bridged by two phenolate ligands. Magnetic susceptibility studies show that ferromagnetic exchange occurs, with the magnetic moment rising from 5.8 mu(B) per Mn(II) center at 300 K to 7.3 mu(B) at 4 K.
