The Raman and infrared spectra of solid TeCl4 and SeCl4 are presented. On the basis of an ionic formulation (MCl3+ and Cl− ions) an assignment of the stretching frequencies of the MCl3+-ion (with nearly C3v symmetry) is given. The results of a rece

Attention is paid to the tentative preparation of NOSbCl4, the only product being NOSbCl6. The temperature dependence in the Raman spectrum of NOSbCl6 is explained in terms of the coupling between NO+ and SbCl6−.

The preparation, Raman and infrared spectra of (PyH)SbCl4, (Et4N)SbCl4, (Bu4N)SbCl4 and (Bu4N)AsCl4 are reported. The spectra of (PyH)SbCl4, (Et4N)SbCl4 and (Bu4N)AsCl4 demonstrate the polymeric behaviour of SbCl4− and AsCl4−; (Bu4N)SbCl4 on the

Although the complex-ions SeCl62−, SeBr62−, TeCl62− and TeBr62− are regular octahedral, the infrared spectra show that some evidence is present for vibronic coupling between ground state and first excited state (dynamic second order Jahn-Tell

The Raman spectra of HSO3Cl in CH3COOH and NaSO3Cl in N,N-dimethylacetamide are recorded. From these spectra the SO3Cl− frequencies are reassigned. The new assignment is in agreement with the Raman spectra of solid (CH3)4N · SO3Cl, SCl4 · SO3, Se

A new synthetic route towards the mixed-metal cluster [OS2Ru(CO)(12)] is described together with the syntheses of its PPh3 and iPr-AcPy (iPr-AcPy = 2-acetylpyridine-N-isopropylimine) derivatives. The molecular structures of the novel clusters [Os2Ru(

The (sub)picosecond time-resolved transient absorption spectra of two triangular [Os 3 (CO) 10 (α-diimine)] clusters have been studied to establish the primary photoprocesses responsible for the formation of biradicals and zwitterions. The TA spectr
