The information on a valence and a coordination states of the 119mSn daughter atoms formed in the cationic and anionic lattice sites of the crystalline lead telluride PbTe and the glassy arsenic telluride As2Te3 from the 119Sb and 119mTe parent isotopes has been obtained using the emission Mössbauer spectroscopy with the 119mTe parent isotopes being in a dynamic radioactive equilibrium with the 119Sb daughter ones. It was found by calculation and experimentally that the proportion of various valent and coordinate states of tin atoms in the crystal and the glass depended on the preparation moment of Mössbauer sources. Moreover, the displacement of a part of the 119Sb daughter atoms from lattice sites of the 119mTe parent isotopes as a result of a radioactive decay was established when bringing into agreement with experimental data.
