Supramolecular Structure of 5-Hydroxyisophthalic Acid-Ethanol 2:1 Solvate

Abstract

A 2:1 5-hydroxyisophthalic acid (HIPA)-ethanol solvate, 2(C₈H₆O₅)·C₂H₆O, was crystallized in the monoclinic space group P2₁/c with a = 13.782(3)Å, b = 8.3300(16)Å, c = 15.755(3)Å, β = 97.366(7)°, V = 1793.8(6)ų, and Z = 4. X-ray crystal structure analysis (R₁ = 0.0740) revealed that the HIPA molecules formed a one-dimensional hydrogen bonded framework along the b-axis containing cavity spaces, into which ethanol molecules were embedded.
