Crystal structure of 9,20-dimethyl-1,8,12,19-tetraazatetracyclo[17.3.1.02,7.013,18]tricosane dihydrate from synchrotron X-ray data
The structure of the title compound, C21H40N4·2H2O, has been determined from synchrotron X-ray radiation data. The asymmetric unit comprises one 12-membered macropolycycle and two lattice water mol-ecules. The macropolycycle contains two cyclo-hexane rings and one 1,3-di-aza-cyclo-hexane ring, all in chair conformations. The C-N and C-C bond lengths are in the ranges 1.4526 (16)-1.4786 (17) and...
متن کاملCrystal structure of trans-cyclohexane-1,2-diammonium chromate(VI) from synchrotron X-ray diffraction data
The structure of the title hybrid compound, (C6H16N2)[CrO4], has been determined from synchrotron data. The organic cation adopts a chair conformation. The inorganic CrO42- anion is slightly distorted owing to its involvement in N-H⋯O hydrogen-bonding inter-actions with neighbouring trans-cyclo-hexane-1,2-di-ammonium cations, whereby the two Cr-O bonds to the O atoms acting as acceptor atoms fo...
متن کاملCrystal structure of hexakis(urea-κO)chromium(III) dichromate bromide monohydrate from synchrotron X-ray data
The title bromide salt, [Cr{CO(NH2)2}6](Cr2O7)Br·H2O, is isotypic to the corresponding chloride salt. Within the complex cation, the Cr(III) atom is coordinated by six O atoms of six urea ligands, displaying a slightly distorted octa-hedral coordination environment. The Cr-O bond lengths involving the urea ligands are in the range 1.9534 (13)-1.9776 (12) Å. The Cr2O7 (2-) anion has a nearly sta...
متن کاملCrystal structure of pentasodium hydrogen dicitrate from synchrotron X-ray powder diffraction data and DFT comparison
The crystal structure of penta-sodium hydrogen dicitrate, Na5H(C6H5O7)2, has been solved and refined using synchrotron X-ray powder diffraction data, and optimized using density functional techniques. Each of the two independent citrate anions is joined into a dimer by very strong centrosymmetric O-H⋯O hydrogen bonds, with O⋯O distances of 2.419 and 2.409 Å. Four octa-hedrally coordinated Na+ i...
متن کاملCapecitabine from X-ray powder synchrotron data
In the title compound [systematic name 5-de-oxy-5-fluoro-N-(pent-yloxycarbon-yl)cytidine], C(15)H(22)FN(3)O(6), the pentyl chain is disordered over two positions with refined occupancies of 0.53 (5) and 0.47 (5). The furan ring assumes an envelope conformation. In the crystal, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains propagating along the b axis. The crystal packing ...
