Abstract
The syntheses of the ‘extended reach’ ligand N,N′-p- phenylenedimethylenebis(4-methylpyridin-2-one) (L) and of a range of its metal complexes with Mn II , Co II , Ni II , Zn II , Cd II , Y III , and lanthanide ions have been accomplished. X-Ray studies showed that in the compound {[MnL 3 ](ClO 4 ) 2 } + n octahedrally co-ordinated manganese centres are connected by L bridges so as to form a three-dimensional array of contiguous rhomboidal ‘boxes’. The analogous compounds with Co II , Ni II , Zn II and Cd II have the same structure. The polymeric compound {[Cu 4 L 5 Cl 8 ]·2MeOH} n forms a complex array of cross-linked chains containing both four- (distorted tetrahedral) and five-co-ordinate (distorted square pyramidal) copper centres in equal proportions.
