In the structure of the title complex, {[CeFe(CN)(6)(H(2)O)(2)]·2H(2)O}(n), the Ce(III) and Fe(III) atoms exhibit square anti-prismatic [CeN(6)(H(2)O)(2)] (site symmetry m2m) and octahedral [FeC(6)] (site symmetry 2/m) coordination geometries, respectively. The metal atoms are linked alternately through the cyanide groups, forming a three-dimensional framework in which the {Ce(2)Fe(2)(CN)(4)} p...

The interaction of selenate, selenite, and chromate with the hydrated surface of gamma-Al(2)O(3) was studied using a combination of macroscopic pH edge data, electrophoretic mobility measurements, and X-ray absorption spectroscopic analyses. The pH edge data show generally increased oxyanion adsorption with decreasing pH, and indicate ionic strength-(in)dependent adsorption of chromate and sele...

The structures of the proton-transfer compounds of 4,5-dichlorophthalic acid (DCPA) with the aliphatic Lewis bases triethylamine, diethylamine, n-butylamine and piperidine, namely triethylaminium 2-carboxy-4,5-dichlorobenzoate, C(6)H(16)N(+) x C(8)H(3)Cl(2)O(4)(-), (I), diethylaminium 2-carboxy-4,5-dichlorobenzoate, C(4)H(12)N(+) x C(8)H(3)Cl(2)O(4)(-), (II), bis(butanaminium) 4,5-dichlorobenze...

In the title compound, (C(4)H(12)N(2))[AuCl(4)](2)·2H(2)O, the Au(III) atom has a square-planar geometry. The piperazinium dication lies on an inversion centre and adopts a typical chair conformation. In the crystal, a combination of N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds results in the formation of a three-dimensional network.

The title complex, [Nd(2)(C(8)H(3)NO(6))(2)(C(8)H(4)NO(6))(2)(H(2)O)(6)]·2H(2)O, consists of dimeric units related by an inversion center. The Nd(III) atom is nine-coordinated by three O atoms from water mol-ecules and six from carboxyl-ate atoms. The 1,2-dicarboxylate acid molecules are in a single and double deprotonation stage and exhibit two coord-in-ation modes, viz. μ(2)-(κ(4), O(1): O(2)...

The title compound, [CrF(3)(C(10)H(8)N(2))(H(2)O)]·2H(2)O, was prepared by the reaction of CrF(3) and 2,2'-bipyridine under hydrous conditions. The metal centre is coordinated in a distorted octahedral mode by two N atoms from the organic ligand, three F atoms and one O atom of a water molecule. . The crystal packing is stabilized by O-H⋯O and O-H⋯F hydrogen-bonding contacts, which form a one-d...
