AbstractTetracyanamidometallates with the general formula RbRE[T(CN 2)4] (RE = La, Pr, Nd, Gd; T = Si, Ge) were prepared by solid state metathesis reactions starting from stoichiometric mixtures of RECl3, A2[TF6], and Li2(CN 2). Reactions were studied by differential thermal analysis that showed ignition temperatures between 360 and 390 C for the formation of RbGd[T(CN2)4] with T = Si and Ge. The powder diffraction patterns of RbRE[Ge(CN2)4] were indexed isotypically to the already known RbRE[Si(CN2)4] compound. IR spectra of RbLa[Ge(CN2)4] were measured and compared with those of RbLa[Si(CN2)4]. 73Ge, 87Rb, and 139La solid state NMR measurements and density functional theory calculations were used to verify the novel homoleptic [Ge(CN2) 4]4- ion. Luminescence properties of Eu3+, Ce3+, and Tb3+ doped samples are reported. © 2013 American Chemical Society.
