Dimeric 1,2-Dioxyphenylene-dichloride (1) crystallizes dimorphically. The already known monoclinic m-form (space group P21/α) is the thermodynamically stable modification and can be obtained by sublimation. The novel triclinic α-form (space group P1̄) is a metastable modification and can be obtained from CH 2 Cl 2  solution. The α-form crystallizes with a = 591.7(5) pm; b = 1457.0(8) pm; c = 991.7(6) pm; α = 96.68(3)°; β = 106.29(3)°; γ = 91.48(3)° and Z = 4 formula units (2 dimers). The molecules of the a- and the m-form are identical with respect to bond distances, bond angles and their conformations, but they are different in their spatial arrangement. The melting point of the α-form is 126.5 °C, of the m-form 140.0 °C. The melt of 1 solidifies as a glass from which the α-form recrystallizes.
