Tribenzoatobismuth(III): a new polymorph
A new polymorph (β) was obtained for an active pharmaceutical ingredient, bis-muth tribenzoate, [Bi(C(6)H(5)CO(2))(3)]. The new β-polymorph is 1.05 times denser than the previously known polymorph [Rae et al. (1998 ▶). Acta Cryst. B54, 438-442]. In the β-polymorph, the Bi atom is linked with three benzoate anions, each of them acting as a bidentate ligand, and these assemblies with C(3) point s...
متن کاملA new polymorph of 5-nitrouracil monohydrate
In the title compound, C(4)H(3)N(3)O(4)·H(2)O, mol-ecules of 5-nitro--uracil are hydrogen bonded in pairs across crystallographic centers of symmetry. The resulting dimers are also hydrogen bonded to the water mol-ecules, forming a three-dimensional network. The pyrimidine ring is almost planar (with a maximum deviation of 0.0156 (9) Å for the one of the N atoms) and the nitro group is rotated ...
متن کاملN-(4-Bromophenyl)acetamide: a new polymorph
A new polymorph of the title compound, C8H8BrNO, has been determined at 173 K in the space group P21/c. The previous room-temperature structure was reported to crystallize in the ortho-rhom-bic space group Pna21 [Andreetti et al. (1968 ▶). Acta Cryst. B24, 1195-1198]. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds forming chains along [010]. Weak C-H⋯π inter-actions are also pres...
متن کاملA new polymorph of dimesitylborinic acid
A new polymorph of dimesitylborinic acid (or hydroxy-dimesitylborane), C(18)H(23)BO, showcasing different crystal packing and symmetry, complements the previously reported polymorph [Weese, Bartlett, Murray, Olmstead & Power (1987 ▶). Inorg. Chem.26, 2409-2413; Entwistle, Batsanov & Marder (2007 ▶). Acta Cryst. E63, o2639-o2641]. The structure of the title compound contains only one mol-ecule i...
متن کاملA new polymorph of N-phenylphthalimide
During an attempt to prepare a cocrystal of N-phenyl-phthalimide, C(14)H(9)NO(2), with N-(2,3,4,5,6-penta-fluoro-phen-yl)phthalimide, a new ortho-rhom-bic polymorph of the first component was obtained. This new form has Z' = 0.5 and the mol-ecule is located around a twofold axis, whereas in the previously reported polymorph (space group Pbca), the mol-ecule has no crystallographically imposed s...
