Supporting information
Benzil monohydrazone (0.224 g, 1 mmol) was dissolved in methanol (20 ml) and to this was added 4-pyridylbenzaldehyde (0.183 g, 1 mmol). The resulting yellowish mixture was heated for 6 h. The solvent was evaporated and the solid was recrystallized from methanol in 80% yield; m.p. 461 K.
H atoms were placed in calculated positions (C-H = 0.95 Å) and were included in the refinement in the riding model approximation, with U(H) set to 1.2U(C). The aromatic ring of the benzoyl unit was refined as a rigid hexagon (C—C = 1.39 Å); attempts to refine the ring as two overlapping rings were unsuccessful. The monoclinic unit cell emulates an orthorhombic unit cell; the use of the twin law (-100 010 001) showed twin fractions are in the ratio 0.63:0.37.

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. |
