A cluster with two chiral tetrahedrane fragments , which are linked through a common tungsten vertex ( 2 ), is formed on heating the tetragonal‐pyramidal trinuclear complex 1 with two μ 3 PS ligands (Cp 4 C 5 H i Pr 4 ). The terminally coordinated PS ligand in 1 is therefore converted into a doubly side‐on bound μ‐η 2 :η 2 ‐PS ligand.
