  A 1H NMR study of the kinetics of the acetonitrile exchange in the complex decakis(acetonitrile)dirhenium(II,II)

  摘要：

  The pseudo-first-order rate constant, k, for the substitution of the eight equatorial acetonitrile ligands in the complex [Re-2(NCCH3)(10)](4+) with acetonitrile has been determined by H-1 NMR in CD3CN solution in the temperature range 298-333 K. The results obtained were: k = (8.3 +/-0.5) x 10(-7) s(-1) (half-life: 9.6 +/-0.5 days) at 298.0 K, DeltaH(double dagger) = 109 +/-2 kJ mol(-1) and DeltaS(double dagger) = 6 +/-6 J mol(-1) K-1. The exchange of the two axially coordinated acetonitrile ligands was found to be fast on the NMR time-scale. (C) 2001 Elsevier Science B.V. All rights reserved.
