Predicted Group 4 Tetra-azides M(N3)4(M = Ti−Hf, Th): The First Examples of Linear M−NNN Coordination

Predicted group 4 tetra-azides M(N3)(4) (M = Ti-Hf, Th): the first examples of linear M-NNN coordination.

Quantum chemical calculations suggest that group 4 tetra-azides M(N(3))(4), where M = Ti, Zr, Hf, and Th, are stable species. They present a unique structural feature; namely, the M-N-N-N fragments are linear. These species are energetically more stable than the corresponding isomers with general formula eta(5)-N(5) -M-eta(7)-N(7), and the Th species, Th(N(3))(4), is the most stable of all. Pos...

First-principles predicted low-energy structures of NaSc(BH4)4.

According to previous interpretations of experimental data, sodium-scandium double-cation borohydride NaSc(BH4)4 crystallizes in the crystallographic space group Cmcm where each sodium (scandium) atom is surrounded by six scandium (sodium) atoms. A careful investigation of this phase based on ab initio calculations indicates that the structure is dynamically unstable and gives rise to an energe...
