Gold oxyfluorides, Au(OF)_n (n = 1–6): novel superhalogens with oxyfluoride ligands

Abstract

In Au(OF)n neutral and anionic species, the highest stabilized oxidation state is limited to +4.

Structure and properties of Li@C 60 –PF 6 endofullerene complex

“…The large NLO response of the complex is expected due to electron transfer from donor Li@C 60 and acceptor BX 4 . In fact, the electron affinity of BX 4 exceeds that of halogen atom, so that it behaves as superhalogen [14][15][16][17][18]. Superhalogens are hypervalent species, which need an extra electron to complete their octet.…”

Superhalogens as Building Blocks of Super Lewis Acids

“…[15] We have also found that there are several superhalogens are available in the literature such as binuclear, trinuclear and polynuclear superhalogens, iron-based magnetic superhalogens, antiferromagnetic binary hyperhalogen, novel superhalogens with metal oxyfluoride ligands, traditional halogen based superhalogens and N5-based aromatic hyperhalogen anions. [16][17][18][19][20][21][22][23][24][25][26] The application of superhalogens are also manifold. It has been observed that they can act as better electrolytes in Li-ion batteries.…”

Reducing Properties of Superalkalis on Pyridinic Graphene Surfaces: a Computational Study

“…Gutsev and Boldyrev proposed the formula , where M is the alkali metal and L is the electronegative atom with valence k. Applications of superalkalis in many fields of material science have drawn much attention in the past decades. Tendency of hyperlithiated compounds to form clusters with non linear optical properties have been shown by various theoretical studies . The electron transfer from superalkalis can be potentially utilized for the conversion of the greenhouse gas CO 2 into useful products, such as methanol fuel and carboxylic acid.…”

“…Tendency of hyperlithiated compounds to form clusters with non linear optical properties have been shown by various theoretical studies. [14][15][16][17] The electron transfer from superalkalis can be potentially utilized for the conversion of the greenhouse gas CO 2 into useful products, such as methanol fuel and carboxylic acid. For example, the superalkali Li 3 F 2 [18] can be employed to easily reduce carbon dioxide CO 2 [19] and nitrogen N 2 [20] with high stability and selectivity.…”
