摘要: Abstract Manganese(III) complexes of stoichiometry MnL(HO2CRCO2)(H2O)n (L=3-CH3Osalpn, 3,5-CH3Osalpn, 5-NO2salpn, 3-Br,5-NO2salpn; R=o-C6H4, CH2, C2H4, C3H6 and n=0–3) have been synthesised. The compounds characterised by elemental analyses, IR spectroscopy, fast atom bombardment mass spectrometry (FAB) magnetic susceptibility measurements. X-ray structure [Mn(3-CH3Osalpn)(HO2CC6H4CO2)]n (1) has determined. hydrogenphthalate ligands link the manganese centres into polymeric chains. Slow evaporation an ethanol solution [Mn(5-NO2salpn)(HO2CC6H4CO2)(H2O)] yielded [{Mn(5-NO2salpn)(OH)(H2O)}{Mn(5-NO2salpn)(HO2CC6H4CO2)(H2O)}]·C2H5OH (2), also crystallographically characterised. two cocrystallised Mn(III) are monomeric, with a distorted octahedral geometry, they interact hydrogen bond π–π stacking. In both 1 2, ligand is monoanionic, however, coordination mode this carboxylate found to differ, showing versatility carboxylates as ligands.
