Creatininium benzoate

Abstract

In the title compound, C4H8N3O+·C7H5O2−, the asymmetric unit comprises one creatininium cation and one benzoate anion. Inter­molecular N—H⋯O hydrogen bonds link the cations and anions into ion pairs, which are further linked into zigzag chains by other N—H⋯O hydrogen bonds. The crystal packing also exhibits weak inter­molecular C—H⋯O hydrogen bonds and dipole–dipole inter­actions.

Creatininium 2-chloroacetate

“…Protonation of the N site of the cation is evident from C-N bond distances and the C-N-C bond angle. Other bond distances and angles are comparable with those found in creatininium hydrogen maleate (Ali et al, 2011a), creatininium cinnamate (Ali et al, 2011b), creatininium hydrogen oxalate monohydrate , creatininium benzoate (Bahadur, Sivapragasam et al, 2007) and bis(creatininium) sulfate (Bahadur, Rajalakshmi et al, 2007). The deprotonation on the -COOH groups of the monochloroacetic acid is confirmed from the -COObond geometry.…”

Creatininium cinnamate

“…The protonation of the N site of the cation is evident from C-N bond distances. The values are comaparable with creatininium oxalate monohydrate , creatininium benzoate (Bahadur, Sivapragasam et al, 2007) and bis(creatininium) sulfate (Bahadur, Rajalakshmi et al, 2007). The deprotonation on the -COOH group of the cinnamic acid is confirmed from -COObond geometry.…”
