3-(4-Hy­droxy-3-meth­oxy­phen­yl)acrylic acid–2,3,5,6-tetra­methyl­pyrazine (2/1)

The asymmetric unit of the title compound, C(8)H(12)N(2)·2C(10)H(10)O(4), contains a tetra­methyl­pyrazine mol­ecule, situated about an inversion center, and two substituted acrylic acid derivatives. The dihedral angle between the phenyl and pyrazine rings is 69.45 (9)°. In the crystal, inter­molecu...

description The asymmetric unit of the title compound, C(8)H(12)N(2)·2C(10)H(10)O(4), contains a tetra­methyl­pyrazine mol­ecule, situated about an inversion center, and two substituted acrylic acid derivatives. The dihedral angle between the phenyl and pyrazine rings is 69.45 (9)°. In the crystal, inter­molecular O—H⋯O, O—H⋯N hydrogen bonds and weak C—H⋯O inter­actions lead to the formation of a supra­molecular network. The acrylic acid side chain is positionally disordered [occupancy ratio 0.852 (7):0.148 (7)].
