The co-ordination modes adopted by N,N'-1,2-xylene-α,α'-diylbis(pyridin-2-one) (o-xbp) with Sc, Y, lanthanides, Th(IV), Mn(II), Fe(III), Co(II) and Zn(II) have been studied.Five representative complexes have been structurally characterised by single-crystal X-ray diffraction.In the monomeric ten-co-ordinate complex *MeOH both o-xbp ligands form eleven-membered chelate rings.In the dinuclear complex *3MeCN pairs of nine-co-ordinate Y atoms are linked by an o-xbp bridge, whilst the other o-xbp ligands form chelate rings.The dinuclear complex 2> forms individual 22-membered rings in which pairs of tetrahedrally co-ordinated Zn atoms are linked by o-xbp bridges.In the iron(III) complex *MeOH the Fe atom in the cation has cis-octahedral co-ordination geometry with the o-xbp ligands forming eleven-membered chelate rings; the anion is tetrahedral.In the cobalt(II) complex I2*2MeOH the o-xbp ligands also chelate but the Co atom has a trans-octahedral geometry in which the two axial ligands are methanol molecules.A distinctive pattern of ligand conformations is observed in this series of compounds.Relevant spectroscopic results are also given.
