摘要：

Clear crystals of anhydrous theobromine (3,7-dihydro-3,7-dimethyl-1H-purine-2,6-dione, C7H8N4O2) were grown by vacuum sublimation and the structure determined. The melting point of anhydrous theobromine has been determined as 620 (1) K, Two molecules in the asymmetric unit form a pseudo-centrosymmetric dimer and pack to form a layered structure of two-dimensional hydrogen-bonded networks.
