  Abstract:

  The title compound was obtained upon the reaction of   2-morpholino-N-[1-(2-pyridyl)ethylidene]ethanamine with CdII   ion
  in the presence of potassium bromide. Similar to the structure of   the analogous CdCl2 complex (Ikmal Hisham et al., 2010),
  the metal center is five-coordinated by the N,N',N"-tridentate   Schiff base ligand and two halogen atoms. The geometry of
  the complexes can be determined by using the index τ = (β-α)/60,   where β is the largest angle and α is the second one around
  the metal center. For an ideal square-pyramid τ is 0, while it is   1 in a perfect trigonal-bipyramid (Addison et al.,1984). The
  τ value in the present structure is calculated to be 0.18,   indicative of a distorted square-pyramidal geometry. The   Cd—Br
  bond lengths in the complex are in agreement with the values   reported in the literature (Bermejo et al., 1999; Bermejo et   al.,
  2003). In the crystal, the adjacent molecules are connected   together via C—H···O and C—H···Br hydrogen bonds, forming
  infinite layers parallel to the ab plane. Moreover an   intramolecluar C—H···Br occurs.
