Nonmonotonous temperature dependence, which suggests formation of closed oligomer(s) via hydrogen-bonds, is detected in heat capacity and dielectric constant of the title compound in the liquid state. The 1H NMR signal of hydroxy protons showed a temperature-dependent fine structure. Quantum-chemical calculations on oligomers of several types revealed that the fine structure is plausibly interpreted as a temperature-dependent formation/destruction of oligomers. A coherent analysis of calorimetric, FT-IR, dielectric, and 1H NMR results shows that the neat liquid of the title compound consists mostly of closed (square) tetramers via H-bonds at lower temperatures, and oligomers with open (or straight) H-bonding and non-H-bonding (monomer) at higher temperature.
