A number of 15 [Fe(Diox·H)2L2] type chelates and [Fe(Diox)3(BOR)2] clathrochelates (Diox·H2 - dimethylglyoxime, glyoxime, propoxime, nyoxime, furyl-dioxime; L-pyridine, alkylpyridine derivatives, diethyl-phenyl-phosphine, diethyl-p-tolyl-phosphine) were obtained and characterized by means of far and middle FTIR and Moessbauer spectroscopic methods. Some structural problems were discussed on the basis of the optical data. The DSC measurements show the higher thermal stability of the clathrochelates without O-H···O intramolecular hydrogen bonds (with asymmetric octahedral structure), as compared to the [Fe(Diox·H)2L2] trans, symmetric chelates containing O-H···O bonds. The kinetic parameters of the thermal decomposition of the complexes have been derived using the nomogram method.
