摘要

The crystal structures of the title compounds were determined by X-ray diffraction. SeCl2+SbCl6-: Space group P2(1)/m, Z=4, structure determination with 1795 observed unique reflections, R=0.022. Lattice dimensions at -80 degrees C: a=940.0, b=1066.3, c=1234.9 pm, beta=102.79 degrees. The compound forms ion pairs with the structure of a double octahedron with linked surfaces. SeBr3+GaBr4-: Space group Pc, Z=2, structure determination with 1461 observed unique reflections, R=0.058. Lattice dimensions at -60 degrees C: a=660.1, b=655.3, c=1431.3 pm, beta=101.17 degrees. The compound crystallizes in the SCl3AlCl4 lattice type. Between the ions there are two relatively short Se ... Br-Ga contacts. PCl4-SeCl5-: space group Ima2, Z=8, structure determination with 1757 observed unique reflections, R=0.029. Lattice dimensions at -50 degrees C: a=1651.6, b=1201.2, c=1166.4 pm. The SeCl5- ions are associated to chains via interionic Se-Cl ... Se contacts along the crystallographic c-axis. (PPh(4)(+))(2)SeCl42-. 2Ch(3)CN: Space group p2(1)/n, Z=2, structure determination with 2578 observed unique reflections, R=0.050. Lattice dimensions at -80 degrees C: a=1288.5, b=726.0, c=2585.8 pm, beta=101.65 degrees. The compound includes planar-tetragonal SeCl42- ions, which almost meet D-4h symmetry. References: 23
