摘要：

A new family of complexes containing bulky pyrazoles substituted in the 3 or the 3 and 5 positions, [RhCl(L(2))(Hpz(R',R''))] (L(2) = NBD, 2CO; R' = Bu(t), Ph, p-CH3OC6H4 (An), R'' = H; R' = Bu(t), Ph, R'' = CH3; R' = R'' = H, CH3), has been obtained. A dynamic behaviour has been observed only in complexes with the less demanding pyrazole ligands, relating with a metallotropic equilibrium when R' = R'' = H, Me, or a diolefin reorientation when R' = Bu(t), Ph, An, R'' = H. The X-ray crystal structure of [RhCl(CO)(2)(Hpz(An))] has been solved, showing a molecular stacking with a Rh-Rh separation of 3.398(3) Angstrom along the one-dimensional chain.
