2,2′-(1,4-Phenyl­ene)bis­(propane-2,2-di­yl) bis­(benzodi­thio­ate)

The title compound, C₂₆H₂₆S₄, shows a dihedral angle of 76.64 (15)° between the central and peripheral benzene rings. An inversion center is located at the centroid of the thio­benzoyl ring. In the crystal, weak C—H...S inter­actions form C(5) chains along [001]. There are no classical hydrogen bonds.

3-(Di­phenyl­amino)­isobenzo­furan-1(3H)-one

In the title isobenzo­furan­one derivative, C₂₀H₁₅NO₂, the planar fused-ring system (r.m.s. deviation for the 10 fitted atoms = 0.031 Å) forms dihedral angles of 63.58 (6) and 63.17 (8)° with the N-bound phenyl rings; the dihedral angle between the planes of these phenyl rings is 85.92 (7)°. In the crystal, mol­ecules are linked by weak C—H...O inter­actions, involving both O atoms, forming helical supra­molecular chains along [001].

2,4,6-Tri­nitro­phenyl 3-bromo­benzoate

In the title picryl-substituted ester, C₁₃H₆BrN₃O₈, the mean plane of the central ester C–O–C(=O)–C fragment (r.m.s. deviation= 0.0186 Å) is rotated by 84.73 (7)° and 19.92 (12)° to the picryl and phenyl rings, respectively. In the crystal, the mol­ecules are linked by C—H...O inter­actions, forming centrosymmetric dimers enclosing R²₂(10) and R²₂(22) ring motifs along [001] and further helical chains of dimers enclosing R²₂(10) ring motifs along [010].
