The formation and structural characterization of the first coordination complex of the tellurophosphorane [tBu(H)NP(μ-NtBu)2P(Te)N(H)tBu] are presented. The silver(I) iodide complex {(I)Ag[tBu(H)NP(μ-NtBu)2P(Te)N(H)tBu]3} (2) was isolated from the reaction of [Li(TMEDA)]2[tBuN(Te)P(μ-NtBu)2P(Te)NtBu)] (1) with AgI in toluene and characterized by X-ray analysis and multinuclear NMR spectroscopy. Complex 2 is comprised of three tellurophosphorane ligands coordinated to AgI in a distorted tetrahedral arrangement [102.90(3)–114.51(5)o]. The P=Te bond lengths of 2.3883(13)–2.4043(17) Å in 2 are slightly elongated compared to those in the free ligand.
