title: 2,3,5-Triphenyl-pyrazine.
abstract: In the title mol-ecule, C(22)H(16)N(2), the pyrazine ring deviates very slightly from planarity [maximum deviation 0.044 (3) Å], tending towards a twist-boat conformation. The phenyl ring at position 3 makes dihedral angles of 64.0 (2) and 45.8 (2)°, respectively, with the phenyl rings at positions 2 and 5. The dihedral angle between the phenyl rings at positions 2 and 5 is 49.7 (2)°. A C-H⋯π inter-action is found in the crystal structure, but no classical hydrogen bonds form.
