Abstract
Two acetylacetonato L-tartrato complexes, mononuclear [Cr(acac)2(Htart)]2– and dinuclear [Cr2(acac)2{(tart)2H}]3– where tart = C4H2O6 4–, were synthesised and characterized by CD or 2H NMR and/or FAB mass spectroscopy. The former complex was found to be the first example to contain bidentate tartrato-O2,O3 bound through the alkoxo and hydroxyl oxygen atoms. The latter complex has a dinuclear structure bridged by two tetradentate tartrato-O1,O2 ligands with a Δ–Δ absolute configuration. The stereo specificity or -selectivity and magnetic behaviour were examined in comparison with analogous complexes.Keywords
