Abstract

1,1′-Di(methylacetato)-2,2′-biimidazole, C₁₂H₁₄N₄O₄, crystallizes from methanol in the space group P2₁/c, where a = 9.535(2), b = 13.385(2), c = 5.1208(8) Å, V = 652.2(2) Å3, and Z = 4. 1,1′-Di(chloroethoxyethyl)-2,2′-biimidazole, C₁₄H₂₀Cl₂N₄O₂, crystallizes from cyclohexane in the space group Pbca, where a = 12.372(2), b = 8.959(2), c = 14.840(2) Å, V = 1644.9(5) ų, and Z = 8. The structures were refined to R = 0.041 (1380 observed reflections) and R = 0.043 (3243 observed reflections), respectively. Both molecules crystallize with coplanar rings and the substituents assume atrans configuration with a center of inversion between the bridging carbon atoms.
