摘要：

A series of manganese(III) complexes of aryl substituted N2O2 donor set Schiff base ligands has been prepared by the aerial oxidation of manganese(II) precursors. The resultant complexes of stoichiometry [MnL]ClO4 . nH(2)O (where n = 1-3) have been thoroughly characterised by elemental analyses, infrared spectroscopy, fast atom bombardment (FAB) mass spectrometry, magnetic susceptibility measurements and paramagnetic H-1 NMR. The crystal structure of [MnL(7)(H2O)(2)]ClO4 ., H2O 1, shows it to consist of a polymeric array of roughly octahedral [MnL(7)(H2O)(2)](+) cations linked cin an intricate network of hydrogen bonds between the perchlorate counterion and the lattice water molecule. This hydrogen bonding is further enhanced by pi-pi stabilisation between the aryl rings of the Schiff base ligands. An attempt is made to rationalise the structural chemistry observed by us for complexes of this type. Copyright (C) 1996 Elsevier Science Ltd
