Parallel interpenetration in novel herringbone sheets formed by Co(II) and Cd(II) complexes with trans-4,4′-azobis(pyridine)
Abstract
The complexes {[M2(µ-4,4′-apy)3(NO3)4]·CH2Cl2}∞ (1, M=Co; 2 M=Cd; 4,4′-apy=trans-4,4′-azobis(pyridine)) form interpenetrated 2-D grids with a (6,3) topology. These sheets exhibit a new herringbone motif in which Co(II) or Cd(II) centres are bridged by co-ordinated 4,4′-apy ligands.
