title: Two triclinic polymorphs of 2,3,5,6-tetrakis(naphthalen-2-ylsulfanylmethyl)pyrazine.
abstract: The title compound, C(48)H(36)N(2)S(4), can be crystallized as two polymorphic structures, (I) and (II), both of which are in the triclinic space group P-1 and possess C(i) symmetry. In the crystal structure of polymorph (I), the adjacent naphthalene moieties are orientated towards one another and are inclined to one another by 78.7 (1) degrees, resulting in weak C-H.pi interactions. In polymorph (II), the adjacent substituents are orientated away from one another, enclosing the pyrazine N atoms. In this way, the S atom of one substituent sits below the plane of the naphthalene ring of the other substituent.
