Nine zinc and cadmium coordination compounds with bis-(1H-tetrazol-5-ylmethyl/ylethyl)-amine were synthesized and structurally characterized, and the fluorescent emission and fluorescence lifetime of complexes 1–9 have been investigated and discussed.

New complexes based on three precursors via in situ nitration have been prepared. Moreover, the solid state UV-vis spectra and band gap energy of those complexes were investigated, and the luminescent properties (1–3, 7 and 8) and magnetic properties (3–6 and 9) were also discussed.

C–H and C–N bonds in tertiary amines were activated by the germanium­(IV) corrole cation [(TPFC)­Ge]+ (TPFC = 5,10,15-tris­(pentafluorophenyl)­corrole) at room temperature. Cleavage of C–H bonds with a unique selectivity for the β- and γ-positions in tertiary amines was observed, in contrary to the well-studied α-position selectivity in C–H bond cleavage promoted by transition-metal compounds. Preliminary mechanism studies using density functional theory (DFT) calculation indicated a nucleophilic substitution pathway for C–N bond activation. Although the mechanism for the C–H bond activation was not clear at the present stage, a cooperative Lewis acid/base reaction pathway was also calculated.
