Crystal structure of 2,2′-({[2-(trityl­sulfan­yl)benz­yl]azane­diyl}bis­(ethane-2,1-di­yl))bis­(isoindoline-1,3-dione)

In the structure of the title compound, C(46)H(37)N(3)O(4)S, the planes of the two isoindoline units make a dihedral angle of 77.86 (3)°. The dihedral angles between the benzyl plane and the isoindoline units are 79.56 (4) and 3.74 (9)°. The geometry at the S atom shows a short [1.7748 (17) Å] S—C(benz­yl) and a long [1.8820 (15) Å] S—C(trit­yl) bond and the C—S—C angle is 108.40 (7)°. N—C bond lengths around the azane N atom are in the range 1.454 (2)–1.463 (2) Å. he crystal packing exhibts two rather ‘non-classical’ C—H⋯O hydrogen bonds that result in stacking of the molecules along the a as well as the b axis and give rise to columnar sub-structures.
