Crystal structure of cyclohexylammonium hydrogen maleate salt hemi-hydrated

Abstract

The compound CyNH₃[HOOC(CH)₂COO]·H₂O has been obtained using one pot-synthesis process by mixing, in methanol, HOOC(CH)₂COOH, CyNH₂ and SnPh₃Cl in a 1:1:1 molar ratio. X-ray diffraction analysis of the compound reveals that in the crystal structure, hydrogen maleate [HOOC(CH)₂COO]^- in cis configuration interacts with [CyNH₃]⁺ cations and water molecules to generate an R₆⁶(22) ring. The interconnections of the rings via simple (N–H··O and O–H··O) and bifurcated (N–H···(O, O)) hydrogen bonds give rise to a 2D supramolecular structure.
