Supramolecular Structure of 5-Hydroxyisophthalic Acid-Acetone 1:1 Solvate

Abstract

A 1:1 5-hydroxyisophthalic acid (HIPA)-acetone solvate, C₈H₆O₅·C₃H₆O, was crystallized in the triclinic space group P1 with a = 6.9655(7)Å, b = 11.2080(11)Å, c = 15.6562(16)Å, α = 83.613(3)°, β = 85.272(3)°, γ = 76.055(2)°, V = 1176.9(2)ų and Z = 4. The X-ray crystal structure analysis (R₁ = 0.0478) revealed that the HIPA molecules formed a one-dimensional hydrogen bonded chain structure via a carboxylic acid dimer motif, along the 1 0 -1 direction. In the (1 0 1) plane, cavity spaces were formed between the chains, where acetone molecules were included.
