The crystal structures of three salts of anionic 5-aminotetrazole are described. The tetramethylammonium salt (P ) forms hydrogen-bonded ribbons of anions which accept weak C–H···N contacts from the cations. The cystamine salt (C2/c) shows wave-

A series of novel melilite-type structured compounds of the general formula Sr2Mg1−xMnxGe2−ySiyO7+δ (0 ≤ x ≤ 1; 0 ≤ y ≤ 2) was produced by conventional solid-state syntheses and subsequently characterized by X-ray powder diffraction (XRP

This paper reports on the synthesis, characterization, and optical properties of a new class of environmentally friendly red pigments based on the tetragonal β-phase of Bi2O3. Stabilization of the metastable β-phase at room temperature has been suc

The structure of (NbO)2P4O13 was solved and refined based on new single-crystal diffraction data revealing considerably more complexity than previously described. (NbO)2P4O13 crystallizes in the triclinic space group P1 with Z = 6. The lattice parame
