Abstract
The structure of 8-hydroxyquinolinatopalladium(II) has been determined by three-dimensional X-ray diffraction. The structure consists of plane-to-plane stacks of planar centrosymmetric 8-hydroxyquinolinatopalladium(II) molecules. The palladium co-ordination is square planar with aromatic carbon atoms, 3·36 Å away, in neighbouring molecules completing a very distorted octahedron. The presence of these carbon atoms is believed to be due to molecular packing rather than a specific interaction of carbon atoms with the metal atom.
