A Spectroscopic and Crystallographic Study of the - Ion

Article abstract of DOI:10.1039/DT9810001061

Preparation of was accomplished by the addition of ReNCl4 to Cl in POCl3.The crystal structure and the i.r. spectra reveal the nearly ideal C_4ν symmetry of the ^- ion.The force constant of the Re<*>N bond is in agreement with the observed Re<*>N length of 1.619(10) Angstroem.The Re-Cl bond distance, 2.322(2) Angstroem, is the first to be reported for a Re^VI case.Unit-cell parameters are in close agreement with those of the other members of the isostructural series: a=12.776(4), c=7.778(3) Angstroem, Z=2, and D_c=1.90 g cm^-3 in the tetragonal space group P4/n.Least-squares refinement gave a final R value of 0.022 for 534 unique observed reflections.
