✦ Synopsis

AbstractIThe i.r. spectra (4000-50cm -~) and laser Raman spectra of solid K3ReO2(CN)4, K3ReO2(t3CN)4 (99°~ t3C enriched), and K3RetSOt60(CN)4 (20% Iso enriched) have been measured. An assignment of the vibrational frequencies for the D4h ion has been made. A normal coordinate analysis was carried out. The refined force constants, and potential energy distributions are tabulated. A symmetry factoring treatment of Re-O force constants has also been shown to be valid for the ReO2(CN)43-ion, and has been used for the Re203(CN)s 4-ion. R, Raman active only; infrared, i.r. active only; minactive; p, polarized; dp, depolarized; ~r, bend -out-of-plane of CN-Re-CN; 8, bend-in-plane of CN-Re-CN.
