Summary

Cobalt(II) and nickel(II) complexes of 4-amino-6-methyl-5-oxo-3-phenylamino-1,2,4-triazine (ATAZ), MX2(ATAZ)2 · 2 H2O (M = Co or Ni; X = Cl, Br, I or NCS), have been isolated. The electronic spectra, magnetic moments and i.r. spectra of the compounds have been studied.Pseudo-octahedral environments are proposed for the complexes: [MX2(ATAZ)2]. 2 H2O (M = Ni or Co; X = Cl or Br) and [CoI2(ATAZ)2(H2O)2], and apseudo-tetrahedral structure for [NiX2(ATAZ)2] · 2 H2O (X = I or NCS) and [Co(NCS)2-(ATAZ)2] · 2 H,O. However, [CoX2(ATAZ)2]. 2 H2O (X = Cl or Br) give acetone solutions containing tetrahedral cobalt(II).
