  Steric effects on the substitution of pentaamine-chromium(III) and -rhodium(III) complexes. Anation reaction rate constants as an indicative of the dissociative shift of the mechanism on crowding the [M(RNH2)5H2O]3+ (M = Rh, R = H, Me, Et, Pr; M = Cr, R = H, Me, Pr) complexes

  摘要：

  The kinetics of the anation reactions of [M(RNH(2))(5)H2O](3+) (M=Rh, R=H, Me, Et, Pr; M=Cr, R=H, Me, Pr) with several ligands (H3PO4/H2PO4-, H3PO3/H2PO3-, CF3COO-, Br-, Cl-, SCN-) have been studied at different temperatures and acidities at I=1.0 M (LiClO4). Results obtained for the anation rate constants and thermal activation parameters are compared with the previously published data for R=H, in order to establish the effects of the amine substituents in the reaction mechanism proposed for the substitution reactions of these complexes. The results obtained are interpreted on the basis of a mechanism where the bond formation process is more important in the substitution on M=Cr complexes than in that of the M=Rh complexes, as already pointed out for the published Delta V-not equal values for the water exchange on these systems. A simple Langford-Gray classification becomes inadequate to describe these situations where the increase of the steric demand of the amine substituents shifts the I-a-I-d classification to the I-d side, although no dramatic changes in the reaction mechanism are found. It is concluded that a More O'Ferrall 'continuous' type of approach to the mechanism classification of the substitution reactions is much more useful in this case.

  found for both anions. The photoanation by Cl− was further studied in alkaline solution and in acid solution containing Co(II). In those solutions the 2Eg state of Cr(III) is quenched. The limiting quantum yield for complete doublet quenching (unquenchable part of the photoreaction) is identical in acid and alkaline solution and has the same value as for the aquation (φnq = 0.14). The quenchable part

  研究了在酸性溶液中Cl-和Br-对[Cr（NH3）6] 3+的光化作用。两种阴离子的量子产率均未发现差异。在含Co（II）的碱性溶液和酸性溶液中进一步研究了Cl-的光化作用。在那些溶液中，Cr（III）的2Eg状态被淬灭。完全双峰淬灭（光反应不可淬灭的部分）的极限量子产率在酸和碱溶液中相同，并且具有与水合相同的值（φnq= 0.14）。光反应的可淬灭部分取决于Co（II）的浓度，与磷光相同。讨论了可能的光化学途径。

  Rate coefficients (k) for aquation of [Co(NH3)5X]2+(X = Br or Cl) in 10% ethanol solutions of some dicarboxylates and sulphate have been determined by spectrophotometry, potentiometric titrations, and e.m.f. changes with time of a cell comprising glass and silver halide electrodes. Similar work has been done with the corresponding complexes of chromium(III) in aqueous solutions. The dissociation constants
