Redetermined structure of diphenylphosphonimidotriphenylphosphorane: location of the hydrogen atoms and analysis of the intermolecular interactions

چکیده
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 mol-ecule. An intra-molecular C-H⋯O inter-action occurs. In the crystal, short C-H⋯O contacts connect the mol-ecules into chains propagating in [011], which are cross-linked via C-H⋯π inter-actions, generating a three-dimensional network. Aromatic π-π stacking also occurs [shortest centroid-centroid separation = 3.6012 (11) Å].

The adsorption behavior of hydrogen for synthesized graphitic carbon nitride (g-C3N4) and graphene oxide nanosheets was compared. The structure of the prepared g-C3N4 and graphene oxide samples were studied using TEM, FT-IR spectroscopy and surface area analysis. Textural results of the prepared nanosheets show that the surface area, total pore volume, and average internal diameter of g-C3N4 an...
