Popis:	This communication reports the dehydration kinetic measurements of HCO3− catalyzed by three inhibitor-containing half-sandwich nickel(II) complexes [TpMe]NiX ([TpMe]=hydrotris(3,5-dimethylpyrazolyl)borate; X−=η2-NO2− (1), N3− (2), NCS− (3)) by employing the stopped-flow techniques at pH 2 (169 M−1 s−1) > 3 (120 M−1 s−1), which is correlated with an increase of the activation energy barrier heights, this being the origin of the variation in the inhibition abilities among the different inorganic anions.
