摘要：

A color change from yellow to red is observed on heating the bipyridinium salt of squaric acid (1). This reversible process is based on a proton transfer during the phase change. According to the Bürgi–Dunitz structure‐correlation principle, the structure of the anion in solid 1 represents a point on the reaction coordinate of the deprotonation of squaric acid.
