Redetermined structure of diphenylphosphonimidotriphenylphosphorane: location of the hydrogen atoms and analysis of the intermolecular interactions
The title compound, C(30)H(25)NOP(2), is a bulky phosphazene derivative. Its previous crystal structure [Cameron et al. (1979 ▶). Acta Cryst. B35, 1373–1377] is confirmed and its H atoms have been located in the present study. The formal P=N double bond is about 0.05 Å shorter than the P—N single bo...

Sumario: | The title compound, C(30)H(25)NOP(2), is a bulky phosphazene derivative. Its previous crystal structure [Cameron et al. (1979 ▶). Acta Cryst. B35, 1373–1377] is confirmed and its H atoms have been located in the present study. The formal P=N double bond is about 0.05 Å shorter than the P—N single bond and the large P=N—P bond angle reflects the steric strain in the molecule. An intramolecular C—H⋯O interaction occurs. In the crystal, short C—H⋯O contacts connect the molecules into chains propagating in [011], which are cross-linked via C—H⋯π interactions, generating a three-dimensional network. Aromatic π–π stacking also occurs [shortest centroid–centroid separation = 3.6012 (11) Å]. |
