چکیده

First examples of coordinatively unsaturated, homoleptic azido complexes of low-valent group 14 elements are reported. A simple strategy uses low-valent precursors, ionic azide transfer reagents and bulky cations to obtain salt-like compounds containing E(N3)3(-) of Ge(II)/Sn(II) which are fully characterised, including XRD. Remarkably, these compounds are kinetically stable at r.t. and isolable in sub-gram quantities.

Lewis base mediated autoionization of GeCl2 and SnCl2.

Cationic and anionic species of heavier low-valent group 14 elements are intriguing targets in main group chemistry due to their synthetic potential and industrial applications. In the present study, we describe the synthesis of cationic (MCl(+)) and anionic (MCl(3)(-)) species of heavier low-valent group 14 elements of germanium(II) and tin(II) by using the substituted Schiff base 2,6-diacetyl...

Reactivity studies of group 15 Zintl ions towards homoleptic post-transition metal organometallics: a 'bottom-up' approach to bimetallic molecular clusters.

Reactions between ethylenediamine (en) solutions of the intermetallic Zintl phases K(3)E(7) (E = P, As) and a series of homoleptic post-transition metal organometallics such as Cu(5)(Mes)(5), M(C(6)H(5))(2) (M = Zn, Cd) and In(C(6)H(5))(3) have yielded a family of novel bimetallic cluster anions. These new species were isolated as [K(2, 2,2-crypt)](+) salts in [K(2,2,2-crypt)](4)Cu(2)E(14) (E =...

Six-Membered Aromatic Polyazides: Synthesis and Application.

Aromatic polyazides are widely used as starting materials in organic synthesis and photochemical studies, as well as photoresists in microelectronics and as cross-linking agents in polymer chemistry. Some aromatic polyazides possess high antitumor activity, while many others are of considerable interest as high-energy materials and precursors of high-spin nitrenes and C₃N₄ carbon nitride nanoma...

Adventures with substances containing metals in negative oxidation states.

A brief history of substances containing s,p- and d-block metals in negative oxidation states is described. A classification of these species and discussions of formal oxidation state assignments for low-valent transition metals in complexes are included, along with comments on the innocent and noninnocent character of ligands in metalates. Syntheses of highly reduced carbonyl complexes formall...
