Crystal structure of tris(piperidinium) hydrogen sulfate sulfate
In the title molecular salt, 3C5H12N(+)·HSO4 (-)·SO4 (2-), each cation adopts a chair conformation. In the crystal, the hydrogen sulfate ion is connected to the sulfate ion by a strong O-H⋯O hydrogen bond. The packing also features a number of N-H⋯O hydrogen bonds, which lead to a three-dimensional network structure. The hydrogen sulfate anion accepts four hydrogen bonds from two cations, where...
متن کاملCrystal structure of (ethoxyethylidene)dimethylazanium ethyl sulfate
In the title salt, C6H14NO(+)·C2H5SO4 (-), the C-N bond lengths in the cation are 1.2981 (14), 1.4658 (14) and 1.4707 (15) Å, indicating double- and single-bond character, respectively. The C-O bond length of 1.3157 (13) Å shows double-bond character, indicating charge delocalization within the NCO plane of the iminium ion. In the crystal, C-H⋯O hydrogen bonds between H atoms of the cations and...
متن کاملImproved Synthetic Route to Unsymmetrically Substituted Phosphinimino-phosphonium Salts. Crystal Structure of Tri-w-butyl- [tris(diethylamino)phosphinimino]phosphonium Chloride
Symmetrically substituted phosphinimino-phos phonium salts [R3PNPR3]X have been known for a long time, and their unusual stability towards acids and bases was demonstrated by the work of Ap pel and Hauss [1], and Schmidbaur and Jonas [2]. The delocalisation of the positive charge in the PNP skeleton and the shielding by the substituents are the main reason for the use of phosphinimino-phos p...
متن کاملCrystal structure of bis(dimethylammonium) hexaaquacobalt(II) bis(sulfate) dihydrate
The title salt, (C2H8N)2[Co(H2O)6)](SO4)2·2H2O, is isotypic with (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O. The Co-O bond lengths in the [Co(H2O)6](2+) complex cation show very similar distances as in the related Tutton salt (NH4)2[Co(H2O)6)](SO4)2 [average 2.093 (17) Å], but are significantly longer than in the isotypic Ni(II) compound (Δd ≃ 0.04 Å). The cobalt cation reaches an overall bond-valence sum ...
متن کاملCrystal structure of bis(dimethylammonium) hexaaquanickel(II) bis(sulfate) dihydrate
In the title salt, (C2H8N)2[Ni(H2O)6)](SO4)2·2H2O, the Ni(II) cation is located on a centre of inversion and exhibits a slightly distorted octa-hedral arrangement of water mol-ecules. The Ni-O bond lengths in the complex [Ni(H2O)6](2+) cation show a distribution as in the related Tutton salt (NH4)2[Ni(H2O)6](SO4)2, but are longer in average [2.056 (13) versus 2.037 (12) Å]. The noncoordinating ...
