SYNTHESIS OF CADMIUM COMPLEX SULFIDES NANOPARTICLES
chemical analysis, IR spectra, TEM and HRTEM
analyses.
The resulted complex sulfides of cadmium may
be included in nanomaterials category, on the basis of
medium diameter (5.59 nm for [Cd2(phen)2(S)]SO4
and 7.64 nm for [Cd2(phen)4(S)]SO4).

On the basis of particles dimensions both complex
sulfides can be included in the nanoparticles category.
In the HRTEM (high-resolution electron micros-
copy) image for [Cd2(phen)2(S)]SO4 (3) (Fig. 9) there
can be observed nanodomains, which have dimen-
sions distributed around 5.27 nm, as it was determi-
nate by analysis of nanoparticles diameters.
From the SAED (selected area electron diffrac-
tion) pattern (Fig. 10) it were measured distances be-
tween planes for [Cd2(phen)2(S)]SO4.

Conclusions
There were synthesised two new complex compounds
of cadmium with 1,10-phenathroline and thiosulfate
ion, having formulas [Cd(S2O3)phen]⋅H2O (1), respec-
tive [Cd(S2O3)phen2]⋅2H2O (2). The both compounds
were characterised by chemical analysis, DTA-TG and
IR methods. The authors proposed mechanism of de-
composition for obtained complex compounds.
On the basis of the results of thermal decomposi-
tion, the complexes were used as precursors for com-
plex sulfides. Thus, by thermooxidative degradation
were obtained complexes [Cd2(phen)2(S)]SO4 (3) and
[Cd2(phen)4(S)]SO4 (4), which were characterised by
