A new polymorph of 5,5′-(ethane-1,2-diyl)bis(1H-tetrazole)
The asymmetric unit of the title compound, C(4)H(6)N(8), contains a quarter of the mol-ecule, which possesses a crystallographically imposed centre of symmetry with all non-H atoms situated on a mirror plane. The crystal packing exhibits inter-molecular N-H⋯N hydrogen bonds and π-π stacking inter-actions between the tetra-zole rings of adjacent mol-ecules [centroid-centroid distance = 3.4402 (1...
متن کاملTribenzoatobismuth(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 second polymorph of [1,2-bis(di-tert-butylphosphino)ethane]dichloridoplatinum(II)
The title complex, [PtCl(2)(C(18)H(40)P(2))], contains a Pt(II) center in an approximately square-planar geometry [cis angle range = 88.09 (3)-91.39 (3)°; twist angle = 1.19 (5)°]. The Pt-P bond lengths of 2.2536 (8) and 2.2513 (8) Å and the Pt-Cl bond lengths of 2.3750 (8) and 2.3588 (8) Å are normal. This crystal form is a polymorph of a structure reported previously [Harada, Kai, Yasuoka & K...
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 کاملA monoclinic polymorph of 1,2-bis[(1-methyl-1H-tetrazol-5-yl)sulfanyl]ethane (BMTTE)
The synthesis and crystal structure of a monoclinic (P21/c) polymorph of the title compound, C6H10S2N8, are reported. The mol-ecule has pseudo-twofold rotational symmetry, with the tetra-zole rings being inclined to one another by 5.50 (6)°. In the crystal, mol-ecules are linked by C-H⋯N hydrogen bonds, forming chains propagating along [101] and enclosing R22(20) ring motifs. The chains are lin...
