Definitive proof of a Ru-C…ClCHCl interaction in the solid state:crystal and molecular structure of[RuCl(CO)(eta~2-C,N-C_6H_4CH=NC_6H_4-4-Me)(PPh_3)_2]centre otCHC1_3

摘要

The solid state structure of[RuCl(CO)(eta~2-C,N-C_6H_4CH=NC_6H_4-4-Me)(PPh_3)_2]centre dot CHCl_3 clearly shows the presence of a RuCl…ClCHCl interaction within the sum of the van der Waals radius.This intraction has the effect of lengthening the Ru-N and shortening the Ru-C bonds of the cycloruthenated Schiff base relative to those observed in the previouslyreported structure of[RuCl(CO)(eta~2-C,N-C_6H_4CH=NC_6H_4-4-Me)(PPh_3)_2]centre dot CH_2Cl_2.
