Abstract

The 1∶2 complex of α-D-glucose and p-tolylboronic acid (1) crystallizes in α-glucofuranose form at room temperature in P212121 space group with one molecule in the asymmetric unit (Z′ = 1). Data collection at 100 K afforded a modulated structure in P21 space group and Z′ = 2. Interestingly, C–H⋯O interactions are shown to relate with multiple molecular conformations and Z′ > 1. There is no change in the crystal structure of α-D-glucofuranose-1,2∶3,5-bis(phenyl)boronate (2) between 100–298 K.
