Abstract top

In the title compound, C28H24N2O4, the dihedral angle between the two rings of the biphenyl unit is 75.34 (9)°. The outer aromatic rings form dihedral angles of 66.96 (1) and 85.69 (8)° with the rings to which they are attached . The molecular structure is stabilized by intramolecular C-H...O and N-H...O hydrogen bonds. In the crystal structure, intermolecular N-H...O interactions are observed.

Comment top

The distortion of diphenyl spacer about central bond not only endows dpa a peculiar characterization to link metal ions or metal clusters into macrocycles or helical chains, but also makes diphenic acid (H2dpa) can deprotonate partially forming hydrogen bonds of carboxylic groups to meet both geometric and energetic requirements. We here report the crystal structure of the title compound.

The C8—C13 and C14—C19 planes form the dihedral angle of 75.34 (9)°, and C1—C6 ring are nearly perpendicular to C14—C19 ring, with a dihedral angle of 85.69 (8)°.The molecular structure is stabilized by C—H···O and N—H···O intramolecular hydrogen bonds.In addition, weak C—H···O intermolecular hydrogen bonds are observed.

Experimental top

The title compound was prepared according to the reported procedure of M. Z. Gao & Gao (2002). Colourless single crystals suitable for X-ray diffraction were obtained by recrystallization from dimethyl sulfoxide.

Refinement top

H atoms were placed in calculated positions with C—H = 0.93 Å, and N—H = 0.86 Å,and refined in riding mode with Uiso(H) = 1.2Ueq(C,N).

Special details top

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

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
