Abstract

The title compound, C(34)H(30)N(4)O(2), lies on an inversion center and consists of two n class="Chemical">3-substituted-1H-indole units linked by a 1,2-dimethyl-enehydrazine bridge. It is one of numerous examples in which two aromatic ring systems are joined by this 4-atom bridge. The geometry of the centrosymmetric bridge is: C(arom)-C = 1.444 (3), C=N = 1.284 (3), N-N = 1.414 (4) Å, C(arom)-C=N = 122.6 (2) and C=N-N = 111.9 (2)°. The nine non-H atoms of the indole unit lie in a plane (δ(r.m.s.) = 0.0089 Å) which is twisted 6.0 (2)° with respect to the hydrazine bridge plane. The benzyl-oxymethyl substituents do not lie in the plane of the rest of the mol-ecule and are in a folded rather than an extended conformation. This is described by the three torsion angles in the middle of the C=N-C-O-C(Bz) group, viz. 98.5 (3), -62.1 (3), and -66.3 (2)°.

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.
