Crystal structure of anagyrine perchlorate
The title mol-ecular salt, C15H21N2O(+)·ClO4 (-), crystallizes with four cations (A, B, C and D) and four anions in the chiral unit cell (space group P21). The alkaloid was isolated from the aerial parts of Genista Hispanica collected in the Samarkand region of Uzbekistan. Each cation is protonated at the N atom that bridges the alkaloid rings C and D. In each cation, ring A is almost planar an...
متن کاملCrystal structure of iron(III) perchlorate nonahydrate
Since the discovery of perchlorate salts on Mars and the known occurrence of ferric salts in the regolith, there is a distinct possibility that the title compound could form on the surface of Mars. [Fe(H2O)6](ClO4)3·3H2O was crystallized from aqueous solutions at low temperatures according to the solid-liquid phase diagram. It consists of Fe(H2O)6 octa-hedra (point group symmetry -3.) and perch...
متن کاملCrystal structure of tin(II) perchlorate trihydrate
The title compound, [Sn(H2O)3](ClO4)2, was synthesized by the redox reaction of copper(II) perchlorate hexa-hydrate and metallic tin in perchloric acid. Both the trigonal-pyramidal [Sn(H2O)3](2+) cations and tetra-hedral perchlorate anions lie on crystallographic threefold axes. In the crystal, the cations are linked to the anions by O-H⋯O hydrogen bonds, generating (001) sheets.

variability, a great number of Schiff base complexes of copper have been subjected to extensive studies. In comparison with organic molecules, metal complexes offer a wider variety of structures, with comparable or, in some cases, higher environmental stability and a much greater diversity of tunable electronic properties, as a result of the coordinated metal center.1 We report here the results...
متن کاملCrystal structure of 2-cyano-1-methylpyridinium perchlorate
The asymmetric unit of the title salt, C7H7N2 (+)·ClO4 (-), comprises two independent formula units. The solid-state structure comprises corrugated layers of cations and of anions, approximately parallel to (010). The supra-molecular layers are stabilized and connected by C-H⋯O hydrogen bonding to consolidate a three-dimensional architecture. A close pyridin-ium-perchlorate N⋯O contact [2.867 (...
