✦ Synopsis

We measured the permanent electric dipole moment of transition metal-(C 6 H 6 ) 2 sandwich complexes in the gas phase. The electric dipole for complexes with Sc, Ti, V, Nb, Ta, and Zr is zero (l < 0:2 D), which is in agreement with a symmetric structure. The electric dipole on the A principal inertial axis of the molecule is 0.7 AE 0.3 D for Co-(C 6 H 6 ) 2 , and 1.3 AE 0.3 D for Ni-(C 6 H 6 ) 2 . This shows that they have an asymmetric structure.
