Experimental
Biphenyl-2,2'-diamine (5 mmol) and cinnamaldehyde (10 mmol) were dissolved in diethyl ether (50 ml). The mixture was stirred for 30 min. Evaporation of the solvent gave a solid that was recrystallized from ethanol twice. Yield: 80%. CH&N elemental analysis. Calculated for C30H24N2: C 87.35, H 5.86, N 6.79%; found: C 87.30, H 5.81, N 9.82%.
Refinement
H atoms were placed in calculated positions [C—H 0.93 Å and Uiso(H) 1.2Ueq(C)], and were included in the refinement in the riding-model approximation. Friedel pairs were merged

Special details
| 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. |
