Diaquabis[8-ethyl-5-oxo-2-(piperazin-4-ium-1-yl)-5,8-dihydropyrido[2,3-d]pyrimidine-6-carboxylato]copper(II) bis[4-(4-carboxyphenoxy)benzoate]
In the title compound, [Cu(C(14)H(17)N(5)O(3))(2)(H(2)O)(2)](C(14)H(9)O(5))(2), the Cu(2+) atom, located on an inversion centre, exhibits a distorted octa-hedral geometry, coordinated by four O atoms from two pipemidic acid ligands in equatorial positions and two water mol-ecules in axial positions. The pipemidic acid ligand acts a bidentate ligand and the single deprotonated 4,4'-oxydibenzoic ...
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 (...
متن کامل4-(3-Carboxy-1-ethyl-6-fluoro-4-oxo-1,4-dihydroquinolin-7-yl)piperazin-1-ium 4-carboxybenzoate–benzene-1,4-dicarboxylic acid (2/1)
In the title compound, C(16)H(19)FN(3)O(3) (+)·C(8)H(5)O(4) (-)·0.5C(8)H(6)O(4), the benzene-1,4-dicarb-oxy-lic acid mol-ecule is located on a centre of symmetry. In the crystal, the mol-ecules and ions are connected by inter-molecular C-H⋯O and O-H⋯O hydrogen bonds and π-π stacking inter-actions [with a centroid-centroid distance of 3.402 (2) Å], generating a three-dimensional supra-molecular ...
متن کامل4-(1-Cyclopropyl-6-fluoro-4-oxo-1,4-dihydroquinolin-7-yl)piperazin-1-ium 2,4,5-tricarboxybenzene-1-carboxylate monohydrate
In the crystal of title compound, C(16)H(19)FN(3)O(+)·C(10)H(5)O(8) (-)·H(2)O, the water mol-ecule and the ions are connected by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds and π-π stacking [centroid-centroid separation = 3.602 (1) Å] between the benzene ring and the pyridine ring, generating a three-dimensional supra-molecular structure.
متن کامل1-Ethyl-6-fluoro-7-(4-methylpiperazin-4-ium-1-yl)-4-oxo-1,4-dihydroquinoline-3-carboxylate hexahydrate
In the title compound, C(17)H(20)FN(3)O(3)·6H(2)O, the pefloxacin (pef) neutral zwitterion is accompanied by six water mol-ecules of hydration. An extensive network of O-H⋯O and N-H⋯O hydrogen bonds help to establish the crystal packing.
