Absorption Line Shape

Nuclear relaxation time measurements and interpretations of absorption line shape in ClF5 and ClOF3 allow one to complete data for these compounds. Thus, the chemical shift between non-equivalent fluorine atoms in ClOF3 has been found equal to 50 ± 2 p.p.m. The coupling constant, chlorine 35Cl–fluorine is 192 Hz for the axial fluorine, and less than 20 Hz for the equatorial fluorines. In addition to other information, such as exchange times between fluorine atoms in ClOF3, and the mean coupling constant chlorine–fluorine in ClOF3 and ClF3, is reported.

Tetrahedral System

A bimetallic Co(ii) compound [Co(dppmO,O)3][CoBr4] consisting of cationic octahedral and anionic tetrahedral units shows a sizable magnetic anisotropy and field-supported slow magnetic relaxation with the relaxation time τ = 0.1–0.3 s at T = 1.9 K.
