A new germanium(II) phosphate, sodium tetra-germanium tris-(phosphate), Na[Ge(4)(PO(4))(3)], has been synthesized by a solid-state reaction. The compound is isotypic with A[Sn(4)(PO(4))(3)] (A = Na, K, NH(4)). It features a [Ge(4)(PO(4))(3)](-) framework made up of GeO(3) pyramids and PO(4) tetra-hedra, which are linked by shared corners, yielding a three-dimensional structure. The crystal stud...

The crystal structures of Na2SeO4·1.5H2O (sodium selenate sesquihydrate) and Na2SeO4·10H2O (sodium selenate deca-hydrate) are isotypic with those of Na2CrO4·1.5H2O and Na2 XSeO4·10H2O (X = S, Cr), respectively. The asymmetric unit of the sesquihydrate contains two Na(+) cations, one SeO4 tetra-hedron and one and a half water mol-ecules, the other half being generated by twofold rotation symmetr...

Inner C-cyanide addition and subsequent addition of a methoxy group were observed in the reactions of Ni(II) N-confused tetra(p-tolyl)porphyrin with sodium methoxide and DDQ.

In the present work, the interaction of three water soluble porphyrins, tetra (p-trimethyle) ammoniumphenyl porphyrin iodide (TAPP) as a cationic porphyrin, tetra sodium meso-tetrakis (p-sulphonatophenyle) porphyrin (TSPP) as an anionic porphyrin and manganese tetrakis (p-sulphonato phenyl)porphinato acetate (MnTSPP) as a metal porphyrin, with DNA have been studied by isothermaltitration microc...

The structure of the title complex, [ZnCl(2)(C(12)H(18)N(2)O(2))], contains a zwitterionic Schiff base ligand. The complex adopts a distorted tetra-hedral coordination geometry around the metal centre with the Schiff base ligand coordinated in a bidentate fashion via the imine N and phenolate O atoms. In the crystal, inter-molecular N-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into chain...

The title compound, lithium/sodium iron(III) bis-[ortho-molyb-date(VI)], was obtained by a solid-state reaction. The main structure units are an FeO6 octa-hedron, a distorted MoO6 octa-hedron and an MoO4 tetra-hedron sharing corners. The crystal structure is composed of infinite double MoFeO11 chains along the b-axis direction linked by corner-sharing to MoO4 tetra-hedra so as to form Fe2Mo3O19...

The title compound, hepta-sodium tetra-chromium(III) tetra-kis-(diphosphate) orthophosphate, was synthesized by solid-state reaction. Its structure is isotypic with that of Na7 M 4(P2O7)4PO4 (M = In, Al) compounds and is made up from a three-dimensional [(CrP2O7)4PO4](7-) framework with channels running along [001]. The three Na(+) cations are located in the voids of the framework. One of the c...

The title compound, sodium trimagnesium bis-(hydrogen phosphate) phosphate, was obtained under hydro-thermal conditions. In the crystal, two types of [MgO6] octa-hedra, one with point group symmetry 2, share edges to build chains extending parallel to [10-1]. These chains are linked together by two kinds of phosphate tetra-hedra, HPO4 and PO4, the latter with point group symmetry 2. The three-d...
