ABSTRACT: The adducts [MBr2(L)n], where M = Fe, Co, Ni, Cu or Zn; L = 1,2,3,4-tetrahydroquinoline (THQ); n = 0.75, 1 or 2 have been obtained from the interaction in hot solution of THQ with the metal(II) bromides. The compounds were characterized by melting points, elemental analysis, thermal analysis and IR spectroscopy. From calorimetric studies in solution, the standard enthalpies of formation of them and several other thermochemical parameters were determined. The mean standard enthalpies of the metal(II)-nitrogen bonds have been estimated.
