Crystal structure of bis(propane-1,3-diammonium) hexafluoridoaluminate fluoride trihydrate
The title compound, (C3H10N2)2[AlF6]F·3H2O, was obtained using the solvothermal method with aluminium hydroxide, HF and propane-1,3-di-amine as precursors in ethanol as solvent. The structure consists of isolated [AlF6](3-) octa-hedra, diprotonated propane-1,3-di-amine cations [(H2dap)(2+)], free fluoride ions and water mol-ecules of solvation. The Al-F bond lengths in the octa-hedral [AlF6](3-...
متن کاملDiammonium aqua(ethylenediaminetetraacetato)iron(II) trihydrate
In the title compound, (NH(4))(2)[Fe(C(10)H(12)N(2)O(8))(H(2)O)]·3H(2)O, the Fe(II) center is in a distorted penta-gonal-bipyramidal geometry. Two carboxyl-ate O and two N atoms from the ethyl-enediaminetetra-acetate (EDTA) ion and one O atom from coordinated water comprise the equatorial plane. Two other carboxyl-ate O atoms from the EDTA ion occupy the apical sites. Both ammonium cations and ...
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.
متن کاملButane-1,4-diammonium bis(pyridine-2,6-dicarboxylato)cuprate(II) trihydrate
In the title compound, (C(4)H(14)N(2))[Cu(C(7)H(3)NO(4))(2)]·3H(2)O or (bdaH(2))[Cu(pydc)(2)]·3H(2)O (where bda is butane-1,4-diamine and pydcH(2) is pyridine-2,6-dicarboxylic acid), the Cu(II) atom is coordinated by four O atoms [Cu-O = 2.0557 (16)-2.3194 (16) Å] and two N atoms [Cu-N = 1.9185 (18) and 1.9638 (18) Å] from two chelating rings of the pydc(2-) anions, which act as tridentate liga...
متن کاملCrystal structure and characterization of pyrroloquinoline quinone disodium trihydrate
UNLABELLED BACKGROUND Pyrroloquinoline quinone (PQQ), a tricarboxylic acid, has attracted attention as a growth factor, and its application to supplements and cosmetics is underway. The product used for these purposes is a water-soluble salt of PQQ disodium. Although in the past, PQQ disodiumpentahydrates with a high water concentration were used, currently, low hydration crystals of PQQ dis...
