From the reaction of NiBr2 and Ph2EtP , it is possible to isolate green crystals of [Ni (Ph2EtP)2 Br2] which has a magnetic moment of 3.2 Bohr magnetons , and red crystals of  [Ni (Ph2EtP)2 Br2] which has a magnetic moment of zero . When either of these is dissolved in dichloromethane at 40 degree C , the resulting solution has a magnetic moment of 2.69 Bohr magneton . . Suggest structure for green and red crystals and offer an explanation for solution magnetic moment ??
