calculations showed that the η5-Ind/Cp coordination mode is always the most stable. However, a molecular dynamics study of the macrocycles conformations revealed that the major conformer of ttcn was a chair, which favoured κ3 coordination. As indenyl complexes undergo slippage with a small barrier (<10 kcal mol−1), the kinetically preferred species [(η3-Ind)Mo(CO)2(κ3-ttcn)]+ (1) is the observed one. The conversion
