Abstract
Single crystal X-ray diffraction studies on CoCl2(pyrazine)2 confirm far-i.r. spectroscopic evidence that in MX2(pyrazine)2[M = Co or Ni; X = Cl, Br, or I] the halogen atoms occupy terminal positions whereas the pyrazine groups are bridging, forming a sheet structure containing six-co-ordinate cobalt atoms.Keywords
