The crystal structure of guanosine dihydrate and inosine dihydrate.
Crystals of the dihydrates of guanosine (C10H13NsOs) and inosine (C10H12N405) are nearly isostructural. They are monoclinic, space group P21, with cell dimensions a= 17·518, b= 11 ·502, c= 6·658 A, P=98·17° (guanosine) and a=17·573, b=11·278, c=6-654A, P=98·23° (inosine). There are two nucleoside molecules and four water molecules per asymmetric unit. Data were collected on an automated diffrac...
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 4-(dimethylamino)pyridinium 4-aminobenzoate dihydrate
In the title hydrated mol-ecular salt, C7H11N2 (+)·C7H6NO2 (-)·2H2O, the cation is protonated at the pyridine N atom and the dihedral angle between the benzene ring and the CO2 (-) group in the anion is 8.5 (2)°. In the crystal, the cation forms an N-H⋯O hydrogen bond to the anion and the anion forms two N-H⋯O hydrogen bonds to adjacent water mol-ecules. Both water mol-ecules form two O-H⋯O hyd...
متن کاملCrystal structure of 3,5-dimethylpyridine N-oxide dihydrate
In the title compound, also known as 3,5-lutidine N-oxide dihydrate, C7H9NO·2H2O, the N-O bond is weakened due to the involvement of the O atom as an acceptor of hydrogen bonds from the two water mol-ecules of crystallization present in the asymmetric unit. Fused R35(10) ring motifs based on O-H⋯O hydrogen bonds form chains in the [010] direction, which are further connected by weak C-H⋯O inter...
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 ...
