In the title compound, [Mo(2)(η(7)-C(7)H(7))(2)(μ-H)(3)], which displays crystallographic mirror symmetry, two (η(7)-C(7)H(7))Mo units are linked along the Mo-Mo axis by three bridging hydride ligands. The Mo-Mo distance is 2.5732 (4) Å. The perpendicular distances of the Mo atoms from the C(7) planes are 1.5827 (8) and 1.5814 (8) Å, with individual Mo-C bond lengths in the range 2.261 (2)-2.2789 (14) Å. Mo-H distances range from 1.77 (3) to 1.85 (4) Å, with Mo-H-Mo angles of 89 (2) and 92 (1)°.
