Far-infrared and Raman spectra of pseudo -tetrahedral complexes of ethylenedimorpholene

The far-i.r. and Raman spectra of a closely related group of pseudo -tetrahedral complexes of general formula [MX 2 EDM] are reported (M = Co II , Ni II , Cu II , Zn II ; X = Cl or Br). EDM, ethylenedimorpholene, acts in these compounds as a bidentate nitrogen donor. The main skeletal vibrations are assigned under the approximate symmetry of the C 2v (MX 2 Y 2 ) point group.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43851/1/11243_2004_Article_BF00623421.pd
