✦ Synopsis


Synthesis and Crystal Structure of [Re 2 Br 4 (Te 2 )(TeBr) 2 (TeBr 2 ) 2 ], a Dinuclear Complex with Te 2 2-, TeBr -, and TeBr 2 Ligands. -Single crystal XRD shows that the title compound (V) crystallizes in the monoclinic space group P2 1 with Z = 4. The structure contains discrete dinuclear molecular units consisting of Re-Re dumbbells each coordinated by a Β΅-Te 2 group and two Β΅-TeBr groups. Additionally each Re atom is coordinated by two terminal Br and a TeBr 2 ligand. -(BECK, JOHANNES;

## Abstract ZrBr~4~ reacts with Te~2~Br in a sealed evacuated ampoule at 210Β°C in quantitative yield to afford (Te^2^~4~^βŠ•^)(Zr~2~Br^2^~10~^βŠ–^) as blueblack, moisture‐sensitive crystals. The crystal‐structure determination shows, that (Te~4~)(Zr~2~Br~10~) consists of planar, nearly square Te^2^~4~^
