Prediction study of the elastic and thermodynamic properties of the SnMg2O4, SnZn2O4 and SnCd2O4 spinel oxides

► SnB2O4 compounds have been investigated using FP-L/APW method. ► The elastic constants and related properties have been predicted. ► The pressure dependence of the elastic constants Cij can be fit by a straight line. ► Thermal and pressure effects on some macroscopic properties have been predicted.
