Final atomic coordinates and displacement parameters (in Â^) Source of material: 6 10"^ mole of 4-iiitrophenol is dissolved in 15 cm^ aqueous solution containing 6 10"^ mole of methylamine. A slow evaporation at room temperature yields yellow orthorhombic prisms. Alternated methylammonium and 4-nitrophenolate ions form helical chains parallel to the ( 100] direction. Two short hydrogen bonds are involved in the chain cohesion: Nl-Hll Ol and
