Summary Cobalt(II) complexes of 4-amino-2,6-dimethyl-5-oxo-3-thioxo-2,3,4,5-tetrahydro-1,2,4-triazine (taz) were prepared by reacting the triazine with the corresponding cobalt salt. The isolated compounds were of the types: [CoCl2(taz)], [CoX2(taz)2(H2O)2] (X = Br or I), [CoX2(taz)2] (X = Br, SCN or NO3) and [Co(taz)2(H2O)2]X2(X = C1O4, BF4 or NO3). Conductance, magnetic and spectroscopic (i.r. and vis.) data were used for structural assignments. Pseudooctahedral and pseudotetrahedral structures are proposed for the complexes, with the triazine molecule acting either as a monodentate nitrogen-donor or a bidentate nitrogen-sulphur-donor ligand.
