“Crystal structure of the free base guanidine determined 148 years after the first synthesis” : A prototype structure unveiled—despite its provocative simplicity, the crystal structure of guanidine has not been previously described. 148 years after the first synthesis of guanidine, we now find two Y‐shaped symmetry‐independent molecules in the unit cell that are interconnected by a hydrogen‐bonding network, which results in a fascinating layered structure (see picture).
