In the crystal structure of the title compound, C26H32N2Si2, there are two independent half-mol­ecules in the asymmetric unit, each molecule lying on a crystallographic inversion center, and hence, in both, the two imine groups are mutually trans. One of the mol­ecules is disordered.

Experimental. One distinct cell was identified using APEX2 (Bruker, 2004). Ten frame series were integrated and filtered for statistical outliers using SAINT (Bruker, 2001) then corrected for absorption by integration using SHELXTL/XPREP (Bruker, 2001) before using SAINT/SADABS (Bruker, 2001) to sort, merge, and scale the combined data. No decay correction was applied.

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. Systematic conditions suggested the ambiguous space group. Structure was phased by direct methods. The space group choice was confirmed by successful convergence of the full-matrix least-squares refinement on F2. A final analysis of variance between observed and calculated structure factors showed little dependence on amplitude or resolution.
