While exploring the chemistry of tellurium‐containing dichalcogenidoimidodiphosphinate ligands, the first all‐tellurium member of a series of related square‐planar E II ( E ′) 4 complexes ( E and E ′ are group 16 elements), namely bis( P , P , P ′, P ′‐tetraphenylditelluridoimidodiphosphinato‐κ 2 Te , Te ′)tellurium(II) (systematic name: 2,2,4,4,8,8,10,10‐octaphenyl‐1λ 3 ,5,6λ 4 ,7λ 3 ,11‐pentatellura‐3,9‐diaza‐2λ 5 ,4λ 5 ,8λ 5 ,10λ 5 ‐tetraphosphaspiro[5.5]undeca‐1,3,7,9‐tetraene), C 48 H 40 N 2 P 4 Te 5 , was obtained unexpectedly. The formally Te II centre is situated on a crystallographic inversion centre and is Te , Te ′‐chelated to two anionic [(TePPh 2 ) 2 N] − ligands in an anti conformation. The central Te II (Te) 4 unit is approximately square planar [Te—Te—Te = 93.51 (3) and 86.49 (3)°], with Te—Te bond lengths of 2.9806 (6) and 2.9978 (9) Å.
