(N',N''Z,N',N''E)-N',N''-[1-(4-Chloro-phen-yl)ethane-1,2-diyl-idene]bis-(3-methyl-1-benzofuran-2-carbohydrazide).

In the title compound, C(28)H(21)ClN(4)O(4), the benzofuran ring systems make dihedral angles of 7.43 (8) and 30.92 (9)° with the chloro-substituted benzene ring. The dihedral angle between the two benzofuran ring systems is 27.41 (7)°. The two benzofuran rings are connected to the chloro-substituted benzene ring through C-N-N=C and C-N-N=C-C bridges which are nearly planar [maximum deviations = 0.003 (1) and 0.037 (1) Å]. An intra-molecular N-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked by N-H⋯(O,N) and C-H⋯O hydrogen bonds into a tape along the c axis and these tapes are further connected by another weak C-H⋯O hydrogen bond into a sheet parallel to the bc plane. π-π inter-actions [centroid-to-centroid distances = 3.4845 (12)-3.6250 (13) Å] are also observed.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.

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.
