The mol­ecule of 4,4'-bis­[2,2-bis(4-methoxy­phenyl)­ethenyl]­bi­phenyl, C44H38O4, has a crystallographic center of symmetry at the midpoint of the bi­phenyl single bond, resulting in an asymmetric unit of one half-mol­ecule. The geometry of the structure is as expected.

Experimental. To determine the structure of the title compound we measured reflective intensities on our CAD4 diffractometer. A stationary anode served as X-ray source. The incident X-ray beam was monochromated with a pyrrolithic graphite crystal. Reflection intensities were measured in an ω/2θ scan mode with a scan angle of (1.30 + 0.70 t g θ). Intensities were measured with an aperture of (2.70 + 0.4 t gθ) Backgrounds were obtained from analysis of the scan profile (Blessing et al., 1974)

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.
