AlN, GaN, and InN have wurtzite structures analogous to cubic BN, but show no analogue of the graphite-type structure of BN. Base stabilized monomeric Group 13/15 compounds. When reacted with water, both compounds produce hydronium ions, making them slightly acidic. Základní údaje; Originální název: Group-13 Azatranes - Structure and Reactivity: Autoři: PINKAS, Jiří, T. L. WANG, R. A. JACOBSON a J. G. Except for the lightest element (boron), the group 13 elements are all relatively electropositive; that is, they tend to lose electrons in chemical reactions rather than gain them. - they all have one electron. The oligomerization tendency of III/V compounds can be suppressed by using sterically demanding ligands and monomeric compounds R 2 MER' … The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh). A Tripodal Benzylene-Linked Trisamidophosphine Ligand Scaffold: Synthesis and Coordination Chemistry with Group(IV) Metals. The +3 oxidation states are favorable except for the heavier elements, such as Tl, which prefer the +1 oxidation state due to its stability; this is known as the inert pair effect. !The element boron has powerful abilities to strengthen, toughen and make fire-resistant glasses, metals, wood, and fibers. Aluminum is an active metal with the electron configuration [Ne] 2s22p1, and usually adopts a +3 oxidation state. Boron can be crystallized from a solution of hydrogen peroxide and borax to produce sodium perborate, a bleach alternative. Therefore, it is found more commonly in its +1 oxidation state. These elements have also been referred to as the triels. Indium has the electron configuration [Kr] 2s22p1 and may adopt the +1 or +3 oxidation state; however, the +3 state is more common. It is poisonous, but used in high-temperature superconductors. The number of hydrides and their thermal stability and the ease of their formation decreases by moving down the group.
