Crystal 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 ...
متن کاملThe 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 کاملA New Uranyl Sulfate Chain in the Structure of Uranopilite
The structure of uranopilite, [(UO2)6(SO4)O2(OH)6(H2O)6](H2O)8, space group P1̄, a 8.896(2), b 14.029(3), c 14.339(3) Å, 96.610(4), 98.472(4), 99.802(4)°, V 1726.1(4) Å3, Z = 2, has been solved and refined on the basis of F2 for all unique data collected with monochromatic MoK X-radiation and a CCD-based detector to an agreement factor (R1) of 7.0%, calculated using 3907 unique observed reflecti...
متن کاملCrystal structure of catena-poly[[copper(II)-μ2-salicylato-[diaquacopper(II)]-μ2-salicylato] dihydrate]
The title compound, {[Cu2(C7H4O3)2(H2O)2]·2H2O} n , contains two copper(II) cations in special positions (one on a twofold rotation axis and one on an inversion centre) and the the salicylate ligand in its dianionic form. By four- and six-coordinate metal coordination, chains are formed parallel to [001], which are extended by O-H⋯O hydrogen bonding into sheets extending parallel to (100). Thes...
