The asymmetric unit of the title salt, C3H6N3 (+)·C2F3O2 (-), contains two independent 3-amino-pyrazolium cations and two independent tri-fluoro-acetate anions. The F atoms of both anions were refined as disordered over two sets of sites, with common occupancy ratios of 0.639 (12):0.361 (12). In the crystal, the cations and anions are linked via N-H⋯O hydrogen bonds, forming chains along [100] ...

In the title compound, K(+)·C7H6BrClNO2S(-)·H2O, the K(+) cation is hepta-coordinated by two water O atoms, four sulfonyl O atoms of four different N-bromo-4-chloro-2-methyl-benzene-sulfonamidate anions, and one Br atom of one of the anions. The S-N distance of 1.584 (3) Å is consistent with an S=N double bond. In the crystal, the anions are linked into layers by O-H⋯Br and O-H⋯N hydrogen bonds.

In the title compound, [K(C7H6Cl2NO2S)(H2O)] n , the K(+) cation is hepta-coordinated by two water O atoms, a sulfonyl O atom from each of four different N,4-dichloro-2-methyl-benzene-sulfonamidate anions and a Cl atom of one of the anions. Further, K-O-K bridges form extensive polymeric chains along the b axis. In the crystal structure, the anions are linked into layers parallel to (100) by O-...

The crystal structure of the title compound, (C(4)H(12)N(2))(2)[BiCl(6)]Cl·H(2)O, consists of piperazinediium cations, [BiCl(6)](3-) anions, Cl(-) anions and uncoordinated water mol-ecules. The Bi(III) cation is coordinated by six Cl(-) anions in a slightly distorted octa-hedral geometry. The diprotonated piperazine ring adopts a chair conformation.

The crystal structure of the title compound, (C(6)H(11)N(2))(3)[EuBr(6)], consists of 1-ethyl-3-methyl-imidazolium cations and centrosymmetric octa-hedral hexa-bromido-europate anions. The [EuBr(6)](3-) anions are located at the corners and face-centres of the monoclinic unit cell. Characteristic hydrogen-bonding inter-actions can be observed between the bromide anions and the acidic H atoms of...

The crystal structure of the title salt, [Fe(C5H5)(C8H13N)](HC2O4), consists of discrete (ferrocenylmeth-yl)di-methyl-ammonium cations and hydrogen oxalate anions. The anions are connected through a strong O-H⋯O hydrogen bond, forming linear chains running parallel to [100]. The cations are linked to the anions through bifurcated N-H⋯(O,O') hydrogen bonds. Weak C-H⋯π inter-actions between neigh...

The influence of the sodium salts of various anions on the spectral properties of acid ferricytochrome c was investigated. It was found that chaotropic anions convert the high spin form of the enzyme into a mixed spin spectral type. The following order of efficiency was established: TBA> TCA> C104> SCN> NO3> Br> Cl(where TBAand TCArepresent tribromoacetate and trichloroacetate ions, respectivel...

The dimeric title compound, [Sm(2)(C(9)H(9)O(3))(6)(C(12)H(8)N(2))(2)], is centrosymmetric and is composed of six 2-phen-oxy-propionate anions and two 1,10-phenanthroline ligands. The Sm(III) atom is coordinated by two O atoms from two bridging anions, four O atoms from two chelating anions and the N atoms of the N-heterocycle in a distorted dodeca-hedral geometry.

Samples containing mixtures of 5 mol % La203 and 95 mol % Al203 were prepared by homogeneous precipitation method with or without the presence of various anions, and calcined at different temperatures in the range of 873-1473 K. Sample prepared by urea hydrolysis in the absence of anions, and calcined at about 1273 K results in the formation of pure lanthanum-,8-alumina (LBA) with high surface ...

Three new, low oxidation state, aluminum-containing cluster anions, Cp*AlnH(-), n = 1-3, were prepared via reactions between aluminum hydride cluster anions, AlnHm (-), and Cp*H ligands. These were characterized by mass spectrometry, anion photoelectron spectroscopy, and density functional theory based calculations. Agreement between the experimentally and theoretically determined vertical deta...
