Copper-succinate-layered hydroxide (CSLH), a new nanohybrid material, was synthesized as an inorganic-organic nanohybrid, in which organic moiety was intercalated between the layers of a single cation layered material, copper hydroxide nitrate. Microporous scaffold carbon material was obtained by thermal decomposition of the nanohybrid at 500 °C under argon atmosphere followed by acid washing p...

Many commercially important catalysts consist of small metal particles dispersed on inorganic oxide surfaces. Although in most cases there is no significant interaction between the metal and the support, strong bonding can be demonstrated in a recently discovered class of supported-metal catalysts. These cases typically involve group VIII metals dispersed on transition metal oxides whose surfac...

The structure of the title hybrid compound, (C6H16N2)[CrO4], has been determined from synchrotron data. The organic cation adopts a chair conformation. The inorganic CrO42- anion is slightly distorted owing to its involvement in N-H⋯O hydrogen-bonding inter-actions with neighbouring trans-cyclo-hexane-1,2-di-ammonium cations, whereby the two Cr-O bonds to the O atoms acting as acceptor atoms fo...

Inorganic cations have been localized in several animal and plant tissues by means of the pyroantimonate fixation procedure (1-3) . We demonstrated that an aqueous solution of potassium pyroantimonate enters the cell without disruption of cell membranes and produces electron-opaque cation-antimonate precipitates in a constant and reproducible manner. The results obtained in mouse testis (3) wer...

A promising approach for the production of highly efficient and stable hybrid perovskite solar cells is employing mixed-ion materials. Remarkable performances have been reached by materials comprising a stabilized mixture methylammonium (MA+) formamidinium (FA+) as monovalent cation. We compare quantify methods stabilizing FA-based perovskites involving additional blending smaller inorganic cat...

The crystal structure of the title compound, C(7)H(20)N(2) (2+)·SO(4) (2-)·H(2)O, is presented, with particular focus on the packing arrangement in the crystal structure and selected hydrogen-bonding inter-actions that the compound forms. The crystal structure exhibits parallel stacking of the diammonium dication in its packing arrangement, together with inorganic-organic layering that is typic...

An inorganic pyrophosphatase was purified over 600-fold to homogeneity as judged by polyacrylamide gel electrophoresis. The enzyme is a tetramer of Mr = 84,000, has a sedimentation coefficient of 5.8S, a Stokes radius of 3.5 nm, and an isoelectric point of 5.7. Like the enzyme of Escherichia coli, the pyrophosphatase appears to be made constitutively. The pH and temperature optima are 8.3 and 8...

In the title compound, (C(7)H(10)N)(2)[SnCl(6)]·2H(2)O, the Sn(IV) atom lies on a site with symmetry 2/m. One of the Cl atoms lies on a mirror plane and the 3-methyl-anilinium cation is also situated on a mirror plane. The water mol-ecule is located on a twofold rotation axis. The H atoms of the methyl and ammonium groups and the solvent water mol-ecule are disordered by symmetry. In the crysta...

Insight into basic principles of cation transport through "molecular channels", and especially details of the related fundamental H2O vehicle function, could be obtained via7Li NMR studies of the Li+ uptake/release processes by the unique porous nanocapsule [{(MoVI)MoVI5O21(H2O)6}12{MoV2O4(SO4)}30]72- which behaves as a semi-permeable inorganic membrane open for H2O and small cations; channel t...

The title complex, (C(5)H(7)N(2))[PbI(3)], consists of a 1-amino-pyridinium cation, disordered about a mirror plane, and a [PbI(3)](-) anion. The Pb(2+) ion (site symmetry ) is surrounded by six I atoms in a slightly distorted octa-hedral coordination. The PbI(6) octa-hedra share faces, building up (∞) (1)[PbI(6/2)] chains running along [010]. The cations are situated between the chains. Coulom...
