Centrosymmetric Dimers

In the crystal structure of the title compound, C11H14N2OS, the six atoms of the central C2N2OS residue are coplanar (r.m.s. deviation = 0.002 Å), which facilitates the formation of an intramolecular N—H...O hydrogen bond, which closes anS(6) loop. The terminal phenyl ring is inclined with respect to the central plane [dihedral angle = 42.10 (6)°]. The most prominent feature of the crystal packing is the formation of {...HNCS}2synthons resulting in centrosymmetric dimers.

In the structure of the title compound, C46H37N3O4S, 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—Cbenzyland a long [1.8820 (15) Å] S—Ctritylbond 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 theaas well as thebaxis and give rise to columnar sub-structures.
