Synthesis and characterization of novel inorganic/organometallic compounds

Ethylenediamine (en) solutions of K4Pb9 react with toluene solutions of ML4 (M = Pt, Pd, L = PPh3; M = Ni, L2= COD) and 2,2,2-crypt to give M@Pb12(2-) cluster anions (M = Pt (1), Pd (2), Ni (3)) as the [K(2,2,2-crypt)]+ salts in low (Ni) to good (Pt) yields. The ions have near perfect Ih point symmetry and have been c…

It's platonic: The Pt centered [Pb12]2− icosahedron (depicted) was prepared from the [Pb9]4− Zintl ion and [Pt(PPh3)4] in good yield. The anion has virtual Ih point symmetry and is a rare example of a free-standing carbon-free aromatic inorganic cluster.

• EMREN NALBANT

The cluster [Ni@Pb10](2-), prepared from Pb9(4-) and Ni(COD)2, contains a new Zintl ion subunit, closo-Pb10(2-), centered by a Ni atom.

The complete reductive cleavage of the triple bond in carbon monoxide was achieved using a lithium disilenide at room temperature. The C-C-coupled product can be regarded as a silanone dimer with pending alkyne and silirene moieties and incorporates two equivalents of CO per disilenide unit. A formation mechanism via…

The reactions of hexachlorocyclotriphosphazatriene, N(3)P(3)Cl(6), with mono- (1 and 2) and bisferrocenyldiamines (3-5), FcCH(2)NH(CH(2))(n)NHR(1) (R(1) = H or FcCH(2)-), produce mono- (6 and 7) and spirocyclic bisferrocenylphosphazenes (8-10). The fully substituted phosphazenes (11-15 and 18-21) are obtained from the…

Ein platonisches Verhältnis Der abgebildete [Pb12]2−-Icosaeder mit einem Pt-Atom im Inneren ensteht in guter Ausbeute bei der Reaktion des Zintl-Ions [Pb9]4− mit [Pt(PPh3)4]. Das Ih-symmetrische Anion ist einer von wenigen isolierten aromatischen anorganischen Clustern, die keine Kohlenstoffatome enthalten.
