A series of complexes of cobalt(II) and 2,9-dimethyl-1,10-phenanthroline (dmp) has been prepared. Complexes of formula CoX2dmp (X = Cl, Br, I, KCS) are monomeric in acetone and camphor and non-electrolytes in nitrobenzene and nitromethane. The magnetic moments and visible absorption spectra favour the assignment of tetrahedral stereochemistry about the Co atom. Complexes containing 2 moles dmp per Co appear to have octahedral arrangements of ligands about the Co atom. These are of the type [CoNO3(H2O)dmp2]X, (X = NO3, ClO4, BPh4) and Co(NCS)2dmp2. The magnetic moments, visible and infrared spectra, and conductances in nitrobenzene and nitromethane support this conclusion. With other mono-dmp complexes (CoX2dmp, X = NO3, �SO4) and bis-dmp complexes {CoXdmp,ClO4,H2O (X = Cl, Br) ; Codmp2(ClO4)2}, stereochemical assignments could not be made.
