Lewis-Base Adducts of Main Group Metal(I) Compounds. XI. Di-μ-iodo-bis(N,N,N′,N″,N″-pentamethyldiethylenetriamine-N,N′,N″-sodium)

Abstract

The synthesis and structural characterization of the 1:1 adduct of sodium(I) iodide and N,N,N′,N″,N″- pentamethyldiethylenetriamine (pmdeta), a novel coordination complex of sodium(I), is recorded. Single-crystal X-ray structure determination shows the compound to be a µ,µ′- diiodo-bridged dimer, with the tridentate base making up the five-coordinate environment of sodium: [( pmdeta )NaI₂Na( pmdeta )]. Crystals are triclinic, P1, a 10.113(2),b 9.470(2), c 8.793(4) Å , α 114.48(2), β 92.09(2), γ 96-65(1)°, Z= 1 dimer ; R was 0.037 for 1837 'observed' reflections.
