Two triclinic polymorphs of 2,3,5,6-tetrakis(naphthalen-2-ylsulfanylmethyl)pyrazine

J. Pacifico and H. Stoeckli-Evans

Abstract: The title compound, C₄₈H₃₆N₂S₄, can be crystallized as two polymorphic structures, (I) and (II), both of which are in the triclinic space group P $\overline 1$ 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)°, resulting in weak C-H [bold 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.

Formula: Two polymorphs of C₄₈H₃₆N₂S₄
