The crystal field splitting energy for a tetrahedral complex (${\Delta }_{\mathrm{t}}$) is related to that of an octahedral complex (${\Delta }_0$) by the formula:

$${\Delta }_{\mathrm{t}}=\frac{4}{9}{\Delta }_0$$

Converting the fraction to a decimal:

$${\Delta }_{\mathrm{t}}=\mathrm{0.444...}{\Delta }_0\approx 0.45{\Delta }_0$$
