Seventeen compounds of cobalt(II), nickel(II), and copper(II) nitrates and thiocyanates with tri-2-pyridylamine (tripyam) and phenyldi-2-pyridylamine (dppa) are reported. The compounds are: [M(tripyam)2(NO3)2](M = Co or Cu), [M(tripyam)2](NO3)2(M = Co or Ni), [Co(tripyam)2][Co(X)4](X = NO3– or NCS–), [Ni(tripyam)(H2O)2NO3](NO3), [Cu(tripyam)(NO3)2], [M(tripyam)2(NCS)2](M = Coor Ni), [Ni(tripyam)(NCS)2], and CuL(CNS)2(L = tripyam or dppa). The spectra of the compounds are discussed in terms of their probable structures and in addition evidence is presented to show that the three possible linkage isomers of CuL(CNS) have been prepared.
