Formation thermodynamics have been investigated for the vapour complexes DyAlnCl3n+3 by quenching experiments within the range T = (654 to 847) K and (p/p°) = (0.4 to 1.8). The results showed that DyAl3Cl12 was the predominant vapour complex at low temperature but DyAl2Cl9 and DyAl3Cl12 coexist at high temperature in the system (DyCl3 + AlCl3). The changes of enthalpy and entropy for the reaction {DyCl3(s) + (v/2)Al2Cl6(g) = DyAlnCl3n+3 (g)}, calculated from the quenching experiments, were DrH °m(DyAl3Cl12, g, 298.15 K) = (17 2 2) kJ•mol -1 , DrS °m(DyAl3Cl12, g, 298.15 K) = -(11 2 3) J•K -1 •mol -1 , DrH °m(DyAl2Cl9, g, 298.15 K) = (92 2 5) kJ•mol -1 , and DrS °m(DyAl2Cl9, g, 298.15 K) = (68 2 7) J•K -1 •mol -1 , respectively.

## Abstract From the two nitrogen‐rich ligands BT^2−^ (BT=5,5′‐bitetrazole) and BTT^3−^ (BTT=1,3‐bis(1__H__‐tetrazol‐5‐yl)triazene), a series of novel rare earth metal complexes were synthesised. For the BT ligand, a vast number of these complexes could be structurally characterised by single‐cryst
