A combined X-ray crystallography and theoretical study of N—HOX (X is =P and —C) hydrogen bonds in two new structures with a (C—O)₂(N)P(=Y) (Y is O and S) skeleton

B. Vahdani Alviri, M. Pourayoubi, A. Farhadipour, M. Nečas and V. Bertolasi

The crystal structures of N,N′-(cyclohexane-1,4-diyl)bis(O,O′-diphenylphosphoramide), C₃₀H₃₂N₂O₆P₂ or (C₆H₅O)₂P(O)(1-NH)(C₆H₁₀)(4-NH)P(O)(OC₆H₅)₂, (I), and N,N′-(1,4-phenylene)bis(O,O′-dimethylthiophosphoramide), C₁₀H₁₈N₂O₄P₂S₂ or (CH₃O)₂P(S)(1-NH)(C₆H₄)(4-NH)P(S)(OCH₃)₂, (II), have been investigated. In the structure of (I), with an (O)₂(N)P(O) skeleton, two symmetry-independent phosphoramide molecules are linked through N—H

O=P hydrogen bonds. In the structure of (II), with an (O)₂(N)P(S) skeleton, the ester O atoms take part in N—H

O—C hydrogen bonds as acceptors; the P=S groups do not participate in hydrogen-bonding interactions. The strengths of these hydrogen bonds were evaluated, using quantum chemical calculations with the GAUSSIAN09 software package at the B3LYP/6-311G(d,p) level of theory. For this, LP(O) to σ*(NH) charge transfers were studied, according to the second-order perturbation theory in natural bond orbital (NBO) methodology, for a three-component cluster of hydrogen-bonded molecules for both structures, including all of the independent N—H

O hydrogen bonds observed in the crystal packing. The details of the intermolecular interactions were studied by Hirshfeld surface maps and two-dimensional fingerprint plots.

Keywords: phosphoramide; thiophosphoramide; X-ray diffraction; N—H

O hydrogen bond; crystal structure; quantum chemical calculations; Hirshfeld surface analysis.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
