X‐ray and electron diffraction studies were made on the two phases of 11‐aminoundecanoic acid, C 11 H 21 NO 2 . Phase I: dihydrate, monoclinic, C 2/ c , z = 8, a = 15.96±0.03, b = 4.71±0.01, c = 35.48±0.08 Å, β = 82.1±0.3°. Phase II: anhydrate, orthorhombic, P 2 1 2 1 2 1 , z = 4, a = 7.526±0.003, b = 4.623±0.003, c = 32.42±0.01 Å.
