Tetrakis-μ-l-alanine-κ8 O:O′-bis[tetraaquaterbium(III)] hexaperchlorate
The asymmetric unit of the title compound, [Tb(2)(C(3)H(7)NO(2))(4)(H(2)O)(8)](ClO(4))(6), contains a dinuclear cation and six perchlorate anions, one of which is disordered. In the cation, the four l-alanine mol-ecules are present in their zwitterionic form and bridge two Tb(3+) ions through their carboxyl-ate O atoms. Each Tb atom is also coordinated by four water mol-ecules in a square-anti-...

The title compound, [Co(2)(O(2))(CH(3)CN)(2)(C(2)H(8)N(2))(4)](ClO(4))(4), consists of centrosymmetric binuclear cations and perchlorate anions. Two Co(III) atoms, which have a slightly distorted octa-hedral coordination, are connected through a peroxido bridge; the O-O distance is 1.476 (3) Å. Both acetonitrile ligands are situated in a trans position with respect to the O-O bridge. In the cry...
متن کاملPoly[tetrakis(μ-1,1,1,3,3,3-hexafluoropropan-2-olato)iron(II)dipotassium]
The title compound, [K2Fe{OCH(CF3)2}4] n , was formed from the reaction of potassium hexa-fluoro-isopropoxide with iron(II) chloride in toluene. The Fe(II) atom has a highly distorted tetra-hedral coordination environment. All four of the non-equivalent hexa-fluoro-isoprop-oxy O atoms link the Fe(II) atoms to one of the K(+) atoms in an alternating chain of Fe-O-K-O fused four-membered rings, w...

The surname of one of the authors and the affiliation of that author in the paper by Mohamed et al. [Acta Cryst. (2009), E66, m193-m194] are corrected.[This corrects the article DOI: 10.1107/S1600536809028955.].
متن کاملl-Alanine hydrochloride monohydrate
Colorless crystals of l-alanine hydrochloride monohydrate, C(3)H(8)NO(2) (+)·Cl(-)·H(2)O, were obtained from a powder sample that had been left standing in a refrigerator for a few years. The structure displays several inter-molecular hydrogen bonds: the hydroxyl O atom is involved in a single hydrogen bond to the chloride anion, while the ammonium group forms one hydrogen bond to the chloride ...
