In ethyl N-[2-(hydroxyacetyl)phenyl]carbamate, C(11)H(13)NO(4), all of the non-H atoms lie on a mirror plane in the space group Pnma; the molecules are linked into simple chains by a single C-H...O hydrogen bond. The molecules of ethyl N-[2-(hydroxyacetyl)-4-iodophenyl]carbamate, C(11)H(12)INO(4), are linked into sheets by a combination of O-H...I and C-H...O hydrogen bonds and a dipolar I...O contact. Ethyl N-[2-(hydroxyacetyl)-4-methylphenyl]carbamate, C(12)H(15)NO(4), crystallizes with Z' = 2 in the space group P-1; pairs of molecules are weakly linked by an O-H...O hydrogen bond and these aggregates are linked into chains by two independent aromatic pi-pi stacking interactions.
在N-[2-(羟基乙酰基)苯基]氨基甲酸乙酯（C₁₁H₁₃NO₄）中，所有非氢原子位于空间群Pnma的一个镜面内；分子通过单一的C-H...O氢键连接成简单的链。N-[2-(羟基乙酰基)-4-碘苯基]氨基甲酸乙酯（C₁₁H₁₂INO₄）的分子通过O-H...I和C-H...O氢键以及偶极I...O接触的组合连接成片。N-[2-(羟基乙酰基)-4-甲基苯基]氨基甲酸乙酯（C₁₂H₁₅NO₄）在空间群P-1中以Z' = 2结晶；分子对通过O-H...O氢键弱连接，并且这些聚集体通过两种独立的芳香π-π堆积相互作用连接成链。
