A Mo 4 butterfly cluster in which a hydrido ligand is bonded to all four metal atoms probably occurs in the anion of the title complex. This anion is accessible from [Mo 2 (OCH 2 t Bu) 6 ] and K[B s Bu 3 H] in the presence of [18]crown‐6. As shown schematically below the H‐ligand serves to couple two Mo Mo units to generate the Mo 4 (μ 4 ‐H)‐containing anion.
