Figure 3.1. IR spectra of the ten compounds NaLa-1, NaCe-2, NaTb-3, Na-4, NaHo-5, Na-6,
Na-7, Na-8, NaLu-9, and Na-10 (from bottom to top).
In this paper, ”Ln” will be used as an abbreviation for the lanthanide ions La 3+ , Ce 3+ ,
Tb 3+ , Dy 3+ , Ho 3+ , Er 3+ , Tm 3+ , Yb 3+ , Lu 3+ as well as for the yttrium ion Y 3+ , since the ionic
radius of the latter falls in the range of lanthanides.
3.A.1.3. X‐ray Crystallography
All crystals were mounted in Hampton cryoloops using light oil, for data collection at low
temperature. Indexing and data collection were performed using a Bruker X8 APEX II CCD
diffractometer with kappa geometry and Mo K α radiation (λ = 0.71073 Å). Data integration
and routine processing were performed using the SAINT software suite. Further data
processing, including multi-scans absorption corrections, was performed using SADABS. 13
Direct methods (SHELXS97) solutions successfully located the W atoms, and successive
Fourier syntheses (SHELXL97) revealed the remaining atoms. 14
