Crystal structure of (1Z)-1-(4-chlorobenzylidene)-5-(4-methoxyphenyl)-3-oxopyrazolidin-1-ium-2-ide
The title mol-ecule, C17H15ClN2O2, is L-shaped with the 4-chloro-benzyl-idene ring almost coplanar with the planar pyrazolidine ring (r.m.s. deviation = 0.020 Å), making a dihedral angle of 4.83 (17)°. The 4-meth-oxy-phenyl ring is almost normal to the mean plane of the pyrazolidine ring and the 4-chloro-benzyl-idene ring, with dihedral angles of 87.36 (17) and 89.23 (16)°, respectively. The py...
متن کاملCrystal structure of 4-hydroxypyridin-1-ium 3,5-dicarboxybenzoate
The structure of the title salt, C5H6NO(+)·C9H5O6 (-), (I), shows that 4-hy-droxy-pyridine has abstracted an H atom from benzene-1,3,5-tri-carb-oxy-lic acid, yielding a pyridinium cation and carboxyl-ate anion. The two ions form an extensive three-dimensional hydrogen-bonded network throughout the crystal. The hydrogen bonds that comprise the core of the network are considered strong, with O-H⋯...
متن کاملCrystal structure of morpholin-4-ium cinnamate
In the anhydrous salt formed from the reaction of morpholine with cinnamic acid, C4H10NO(+)·C9H7O2 (-), the acid side chain in the trans-cinnamate anion is significantly rotated out of the benzene plane [C-C-C- C torsion angle = 158.54 (17)°]. In the crystal, one of the the aminium H atoms is involved in an asymmetric three-centre cation-anion N-H⋯(O,O') R 1 (2)(4) hydrogen-bonding inter-action...
متن کاملCrystal structure of 3-[4-(pyrimidin-2-yl)piperazin-1-ium-1-yl]butanoate
The title compound, C12H18N4O2, crystallizes in the zwitterionic form with protonation at the N atom of the piperazine ring bearing the carboxylate group. The piperazine ring adopts a slightly distorted chair conformation. In the crystal, N-H⋯O hydrogen bonds are observed, forming chains along [010]. The packing is consolidated by C-H⋯O inter-actions, which generate a three-dimensional network.
متن کاملCrystal structures of 4-(pyrimidin-2-yl)piperazin-1-ium chloride and 4-(pyrimidin-2-yl)piperazin-1-ium nitrate
The title salts, C8H13N4 (+)·Cl(-), (I), and C8H13N4 (+)·NO3 (-), (II), contain linked pyridinium-piperazine heterocycles. In both salts, the piperazine ring adopts a chair conformation with protonation at the N atom not linked to the other ring. In the crystal of (I), weak N-H⋯Cl inter-actions are observed, leading to zigzag chains along [100]. In the crystal of (II), both H atoms on the NH2 (...
