Abstract

The anhydrous 1∶2 triglyme:Dichloropicric acid adduct is triclinic, space group $$P\bar 1$$ ; at 24°Ca=8.703(5),b=10.381(4), c=10.404(3) A, α=114.42(3), β=99.69(5), γ=106.40(6)°,D x=1.656 g cm−3, V = 776(2)A3,Z=1. Bond lengths and angles are normal except that one C−C−O−C torsion angle in the triglyme is approximately 90° rather than the expected 60 or 180°. Each phenolic OH group hydrogen bonds with a terminal OCH3 of the polyether. The O...O distance, 2.557(3) A, is in fair agreement with the 2.52 A estimated from the single observed IRv (OH) stretch at 1714 cm−1.
