The thermoanalytical study of some MeHm

complexes (Hm = histamine;
x = 1, 2) and MeHm
x
(NO
3)
2 (
x = 2, 4) with Co
(II), Ni
(II) and Cu
(II) is reported. By TG-FTIR coupled analysis, the decomposition steps are analyzed and the intermediate reactions are proposed. Results of ESCA analysis for all Ni
(II) compounds indicate correct atomic ratios between organic and inorganic nitrogen and are useful for determining metal coordination states.
