2-(2-Methoxyphenoxy)pyrazine [PDF]
Acta Crystallographica Section E Structure Reports Online, 2011 A significant twist is observed in the title molecule, C(11)H(10)N(2)O(2), as seen in the dihedral angle between the pyrazine and benzene rings of 72.79 (8)°. The meth-oxy group is almost coplanar with the benzene ring to which it is attached [C-O-C-C torsion angle = 175.83 (15)°].

2-(4-Methoxyphenoxy)pyrazine [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 In the title compound, C(11)H(10)N(2)O(2), the aromatic rings are almost orthogonal to each other [dihedral angle = 86.97 (8)°], with the benzene ring orientated to face one of the pyrazine N atoms. In the crystal, centrosymmetrically related pairs are connected via pairs of C—H⋯π interactions and the dimeric units thus formed pack into undulating ...
