Zur Elektronenstruktur hochsymmetrischer Verbindungen der f-Elemente. 40 [1] Parametrische Analyse des Kristallfeld-Aufspaltungsmusters von Tris(hydrotris(1-pyrazolyl)borato)neodym(III)
The absorption spectrum of tris(hydrotris(1-pyrazolyl)borato)neodymium(III) (NdTp3) was run at room and low temperatures. From the spectra obtained, a truncated crystal field (CF) splitting pattern could be derived, and simulated by fitting the free parameters of a phenomenological Hamiltonian achieving an r.m.s. deviation of 11.0 cm-1 for 48 assignments. The parameters used allow the estimation of the ligand field strength experienced by the Nd3+ central ion, the insertion of the Tp ligand into empirical nephelauxetic and relativistic nephelauxetic series, and the set-up of experimentally based nonrelativistic molecular orbital schemes in the f range.
