Crystal structure of 2,5-dimethylanilinium hydrogen maleate
The crystal structure of the title salt, C8H12N(+)·C4H3O4 (-), consists of a 2,5-di-methyl-anilinium cation and an hydrogen maleate anion. In the anion, a strong intra-molecular O-H⋯O hydrogen bond is observed, leading to an S(7) graph-set motif. In the crystal, the cations and anions pack in alternating layers parallel to (001). The ammonium group undergoes inter-molecular N-H⋯O hydrogen-bondi...
متن کاملCrystal structure of 2-methylpiperazine-1,4-diium bis(hydrogen maleate)
In the title salt, C5H14N2 (2+)·2C4H3O4 (-), the asymmetric unit contains two independent 2-methyl-piperazinium dications, which comprise a racemic pair, and four hydrogen maleate monoanions. In the roughly planar hydrogen maleate anions, intra-molecular O-H⋯O hydrogen bonds generate S(7) rings. In the crystal, the four independent anions are linked to the 2-methyl-piperazinium cations through ...
متن کاملCrystal structure of levomepromazine maleate
The asymmetric unit of the title salt, C19H25N2OS(+)·C4H3O4 (-) [systematic name: (S)-3-(2-meth-oxy-pheno-thia-zin-10-yl)-N,N,2-tri-methyl-propanaminium hydrogen maleate], comprises two (S)-levomepromazine cations and two hydrogen maleate anions. The conformations of the two cations are similar. The major difference relates to the orientation of the meth-oxy substituent at the pheno-thia-zine r...
متن کامل2-Methylimidazolium hydrogen maleate
Mol-ecules in the title compound, C(4)H(7)N(2) (+)·C(4)H(3)O(4) (-), are linked by inter-molecular N-H⋯O hydrogen bonds into one-dimensional chains parallel to [101]. These chains are in turn linked by an R(2) (2)(8) motif, formed by weak C-H⋯O hydrogen bonds, into corrugated sheets running parallel to (10). These sheets are further linked by weak inter-molecular C-H⋯O hydrogen bonds, forming a...
متن کاملFlunarizinium hydrogen maleate
In the cation of the title salt {systematic name: 4-[bis-(4-fluoro-phen-yl)meth-yl]-1-[(2E)-3-phenyl-prop-2-en-1-yl]piperazin-1-ium hydrogen maleate}, C26H27F2N2 (+)·C4H3O4 (-), the protonated piperazine ring is in a chair conformation. The dihedral angle between the 4-fluoro-phenyl rings is 68.2 (2)°. An intra-molecular O-H⋯O hydrogen bond occurs in the anion. In the crystal, N-H⋯O, C-H⋯O and ...
