Ethyl N-[2-(hydroxyacetyl)phenyl]carbamate, ethyl N-[2-(hydroxyacetyl)-4-iodophenyl]carbamate and ethyl N-[2-(hydroxyacetyl)-4-methylphenyl]carbamate.

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.
