The conformation of tetramethyl-N,N′-bis(o-methoxyphenyl)cyclodisilazane was investigated by 13C NMR in solution and by X-ray diffraction in the solid state. The conformation in solution compares to that of o-methoxyaniline. The phenyl and the cyclodisilazane ring forms a dihedral angle of 7.4° and there is a non-bonded Si ⋯ O distance of 2.73 Å in the crystal. The molecular geometry suggests an analogy to S ⋯ O non-bonded interactions often observed in organosulphur chemistry.
