ABSTRACT: Complexes of general formula [MBr2(3-clan)n]
(where M is Fe, Ni, Cu or Zn; 3-clan = m-chloroaniline; n is 1.5 or 2) were
prepared and their characteristic properties, such as capillary MP; C, H, N, Br
and metal contents; TG/DTG and DSC curves; and IR and electronic spectra were
determined. By calorimetric measurements in solution, the values of some
thermodynamic parameters of the complexes were determined. From these values,
the standard enthalpies of the metal-nitrogen coordinated bonds were calculated, and
the standard enthalpies of the formation of the gaseous phase complexes
were estimated.
