N,N′-Bis(2-amino­phen­yl)-3,4-diphenyl­thio­phene-2,5-dicarboxamide acetonitrile solvate

In the title solvate, C(30)H(24)N(4)O(2)S·CH(3)CN, the substituted thiophene possesses approximate C(s)(m) intrinsic symmetry, with the mirror plane passing through the S atom and the mid-point of the (Ph)C—C(Ph) bond. Despite the main backbone of the mol­ecule being a long chain of conjugated bonds, it adopts a non-planar conformation due to the presence of various intra- and inter­molecular hydrogen bonds. The hydrogen bonds result in twist configurations for both the amido and amino­phenyl fragments relative to the central thio­phene ring. There are two intra­molecular N(amine)—H⋯O hydrogen bonds within the thio­phene-2,5-dicarboxamide mol­ecule that form seven-membered rings. In the crystal, the thio­phene-2,5-dicarboxamide mol­ecules form inversion dimers by four amide–amine N—H⋯N hydrogen bonds. The dimers are further linked into layers propagating in (100) both directly (via N(amine)—H⋯O hydrogen bonds) and through the acetonitrile solvate mol­ecules (via amine–cyano N—H⋯N and C(Me)—H⋯O inter­actions).
