Abstract
In the solid state l-cis-[M(en)2Cl2]Cl [M=cobalt(III) or chromium(III)] undergoes thermal racemisation smoothly at 158 °C without any cis-trans interconversion. The values of krac, ΔH‡ and ΔS‡ are 6 × 10-6s-1, 218 kJM-1 and 156.1 JK-1M-1 for the cobalt(III) complex and 3.5 × 10-5s-1, 229.7 kJM-1 and 197.9 JK-1M-1 for the chromium(III) complex, respectively. The results are only in accord with a rhombic twist mechanism of the type originally proposed by Ray and Dutt for [M(AA)3] complexes. © 1985 VCH Verlagsgesellschaft mbH.
