In the title compound, the Mo VI cation is located on a mirror plane and has a distorted tetrahedral coordination geometry. The Mo N bond length is 1.633 (6) Å.
In the title compound, [Mo(C 6H 18NSi 2)(C 3H 9OSi) 2N], the Mo VI cation is located on a mirror plane and is coordinated by a nitride anion, a 1,1,1-trimethyl- N-(trimethylsilyl)silanaminate anion and two trimethylsilanolate anions in a distorted tetrahedral geometry; the N atom and two Si atoms of the 1,1,1-trimethyl- N-(trimethylsilyl)silanaminato anionic ligand are also located on the mirror plane. The Mo N bond length of 1.633 (6) Å is much shorter than the Mo—N single-bond length of 1.934 (7) Å. No hydrogen bonding is observed in the crystal structure.
