Triggering water exchange mechanisms via chelate architecture. Shielding of transition metal centers by aminopolycarboxylate spectator ligands.
TL;DR: The data for the mentioned tmdta complexes indicate a dissociatively activated exchange mechanism in all cases with a clear relationship between the sterical hindrance that arises from the ligand architecture and mechanistic details of the exchange process for seven-coordinate complexes.

Effect of chelate dynamics on water exchange reactions of paramagnetic aminopolycarboxylate complexes.
TL;DR: A relationship between chelate dynamics and reactivity seems to be operative, since the CyDTA complexes exhibited significantly slower reactions than their EDTA counterparts, and this mechanism is reliably assigned as a dissociative interchange (I d) mechanism.

Elucidation of the Solution Structure and Water-Exchange Mechanism of Paramagnetic [FeII(edta)(H2O)]2-
TL;DR: The lability and structural dynamics of [Fe(II)(edta)(H(2)O)](2-) (edta = ethylenediaminetetraacetate) in aqueous solution strongly depend on solvent interactions and high-pressure NMR techniques were applied to elucidate the intimate nature of the water-exchange mechanism.

TL;DR: The crystal structure of the as-yet-unknown salt K[Fe(III)(cydta)(H(2)O)](-) where cydta = (+/-)-trans-1,2-cyclohexanediaminetetraacetate, has been resolved and the reaction was found to consist of two steps and resulted in the formation of a purple Fe(III) side-on-bound peroxo complex.

Quantum Chemical Analysis of the Enantiomerisation Mechanism of Complexes of the Type [MII(XU)4]F+ (M = Pt, Pd, Ni; X = S, Se, Te;U = urea)
TL;DR: In this paper, the enantiomerization pathway for the C4-symmetric SiF6 complex and derivatives is explored by density functional theory and the activation barrier for the one-step process from C4 to C4′ via a C4 transition state is computed.
