title: Studies on the reactivity of group 15 Zintl ions with carbodiimides: synthesis and characterization of a heptaphosphaguanidine dianion.
abstract: Reaction of the hydrogenheptaphosphide dianion, [HP(7)](2-), with one equivalent of bis(2,6-diisopropylphenyl)carbodiimide yielded the exo-functionalized cluster [P(7)C(NDipp)(NHDipp)](2-) (Dipp = 2,6-diisopropylphenyl). This species was characterized by single crystal X-ray diffraction, multielement NMR spectroscopy and electrospray mass-spectrometry. DFT calculations on the dianion were also conducted.
