Structure and spectroscopy of Tb[Au(CN)(sub 2)](sub 3).3H2O
Article Abstract:
The compound Tb[Au(CN)(sub 2)](sub 3).3H2O crystallizes in a layered structure in the hexagonal space group P6(sub 3)/mcm with the 9-coordinate environment of Tb(super 3+) comprising six (CN-) and three OH2 in a tricapped trigonal prism. Although C triple-bond N stretching vibrations show exclusive infrared or Raman activity in Tb[Au-(CN)(sub 2)](sub 3).3H2O, both of these infrared and Raman active modes are observed in the two-center vibronic transitions.

Electronic spectra of [Cs.sub.2]NaYb[F.sub.6] and crystal field analyses of Yb[X.sub.6.sup.3-] (X = F, Cl, Br)
Article Abstract:
The well-resolved electronic absorption spectrum of octahedrally coordinated [Yb.sup.3+] in [Cs.sub.2]NaYb[F.sub.6] has enabled the crystal field energy level diagram to be deduced. The results have shown that the inclusion of configuration interaction with a charge-transfer configuration provides an exact energy level datafit and also indicates consistent trends in parameter values for the [Cs.sub.2]NaLn[Cl.sub.6] (Ln = Er, Tm, Yb) systems.
