## Abstract The water exchange of [V(H~2~O)~6~]Cl~2~ in aqueous solution has been studied as a function of temperature and pressure (up to 250 MPa), by measuring the ^17^O‐FT‐NMR. line‐widths of the free water resonance at 8.13 MHz. The kinetic parameters obtained are __K__ = 87±4 s^−1^, __ΔH__^\*^
