The Novel

By reacting Na2O, which was produced in situ from NaN3 and NaNO2, with reactive ZnO in the solid state, the synthesis of Na2ZnO2 has been achieved. Na2ZnO2 is metastable up to about 750°C. The novel sodium zincate crystallizes in the spaceogroup P21/c (No. 14) with the lattice parameters a = 7.7352(2), b = 5.9782(2), c = 5.7248(2) Å, β = 94.934(3)°, Z = 4. According to a single crystal structure determination it is an representative of the anti type of the Ln2S2O (Ln = Er, Tm, Yb, Dy) structure.

Space Group

A new modification of Na2Zn2O3 has been synthesized via solid state reaction. According to the single crystal structure determination, the compound crystallizes in the space group P43212 (No. 96) with lattice parameters a = 6.1812(2), c = 9.4479(4) Å, Z = 4. The structure consists of ZnO4 tetrahedra connected via edges and corners forming a threedimensional network. The structure can be described as an distorted anti spinel.

Structure Solution

AbstractThe structures of cetylpyridiniumammonium bromide (CPyB) and cetylquinuclidinium bromide (CQB), two tetraalkylammonium bromide surfactants, are reported. In particular, whereas the structure solution of CPyB was carried out through conventional single-crystal diffractometry, the structure of CQB has been determined by means of powder diffractometry. CPyB crystallizes in
