The relationship between the zero‐field splitting parameter D and the C 3v crystalline potential components for Mn 2+ ions is established by using the parametrization d‐orbital theory proposed by Zhao et al. The pressure dependence of D of Mn 2+ in Na 2 ZnCl 4 · 3 H 2 O is calculated. The results agree well with the values measured experimentally indicate that the D ‐value increase with increasing pressure is caused most dominately by changing in the angle θ and next by the change in the bond length R under pressure.
