The poly-phosphate Li2Mn(PO3)4 was synthesized and its structure characterized from powder diffraction data by Averbuch-Pouchot & Durif [J. Appl. Cryst. (1972), 5, 307–308]. These authors showed that the structure of this phosphate is isotypic to that of Li2Cd(PO3)4, as confirmed by the present work. The structure is built from infinite zigzag polyphosphate chains, [(PO3)]n, extending along [010]. These polyphosphate chains are connected by sharing vertices with MnO6 octa­hedra (site symmetry .m.) and Li2O7 polyhedra, which form also chains parallel to [010]. Adjacent chains are linked by common vertices of polyhedra in such a way as to form porous layers parallel to (100). The three-dimensional framework delimits empty channels extending along [010].

The structure of the title compound is characterized by the presence of two different anions, (PO4)3− and (P2O7)4− with an eclipsed conformation. The crystal structure consists of edge-sharing [NiO6] octa­hedra forming an [Ni3O14] chain running parallel to [001]. Adjacent chains are connected through edges and apices to PO4 and P2O7 groups in such a way as to build a three-dimensional host lattice. The resulting framework presents inter­secting tunnels running along [010] and [101] in which the 11-coordinated potassium cation is located. The crystal structure of this new phosphate probably represents a new structural type.

The asymmetric unit of the title organic–inorganic molecular salt, C6H18N22+·SiF62−, consists of one anion and one cation together with half of each of two cations and two anions located on inversion centres. The SiF62− octa­hedral anions are arranged to form sheets parallel to (011), which are linked into a three-dimensional network by the organic cations through N—H...F hydrogen bonds.

In the title compound, C14H10N4O6S, the indazole ring system is almost perpendicular to the tosyl ring, as indicated by the dihedral angle of 89.40 (9)° between their planes. The dihedral angles between the indazole system and the nitro groups are 57.0 (3) and 31.9 (3)°. In the crystal, mol­ecules are linked by C—H...O inter­actions, forming chains running along [100].
