Abstract
- This paper aims to review recent advances on synthesis, crystal structures, thermal, spectroscopic, phase transitions, optical, dielectric, and catalysis properties of hydrate and anhydrous alkylenediammonium halogenometallates materials (Metal: Bi, Sb, Halogen: Cl, Br, I). These hybrid materials present rich structural diversities based on octahedra forming infinite zero dimensional, 1-dimensional chains, 2-dimensional layers, discrete bioctahedra, and discrete tetramer units. The effect, contribution and importance of hydrogen bonding N–H ... X (X: Cl, Br, I) are reviewed in terms of solid state relationship. Particularly, a comparative study is made on hydrate and anyhdrous aliphatic chlorobismuthates with alkylenediammonium <superscript>+</superscript>NH<subscript>3</subscript>(CH<subscript>2</subscript>)<subscript>n</subscript>NH<subscript>3</subscript><superscript>+</superscript> based on structural data and V/Z variation with (CH<subscript>2</subscript>)<subscript>n</subscript> chains (n = 2–8, 12), and variation of BiCl<subscript>6</subscript><superscript>3−</superscript> Raman frequencies modes versus (CH<subscript>2</subscript>)<subscript>n</subscript> chains (n = 3–8). Hydrate salts with (n = 3, 12) consist of isolated BiCl<subscript>6</subscript><superscript>3−</superscript> anions and two water molecules, against others ones with isolated anionic chains [BiCl<subscript>5</subscript><superscript>2−</superscript>]<subscript>n</subscript> or Bi<subscript>2</subscript>Cl<subscript>10</subscript><superscript>4−</superscript> dimers, formed by distorted octahedra BiCl<subscript>6</subscript><superscript>3−</superscript> sharing corners, vices or edges. The reviewed optical and electronic band gaps suggested interesting compounds with band gaps (1.85–2.4 eV), as suitable materials in optoelectronic properties, photoactive layer in solution-processed photovoltaics, and bio-imaging or photovoltaic applications. It was concluded that iodobismuthate salts have generally the lowest bands gap, compared to that of bromo and chlorobismuthate slats. Catalysis proprieties are reviewed n fast (RhB) degradation under dark conditions for (C<subscript>4</subscript>N<subscript>2</subscript>H<subscript>7</subscript>)<subscript>4</subscript>Bi<subscript>2</subscript>Cl<subscript>10</subscript>, (C<subscript>5</subscript>H<subscript>9</subscript>N<subscript>2</subscript>)BiI<subscript>4</subscript>, and {(H-BPA)<subscript>4</subscript>·[(BiI<subscript>6</subscript>)I<subscript>13</subscript>]·2I<subscript>3</subscript>}<subscript>n</subscript>, and in organic salts synthesis under solvent-free conditions. Herein NH<subscript>3</subscript>(CH<subscript>2</subscript>)<subscript>n</subscript>NH<subscript>3</subscript>BiCl<subscript>5</subscript> (n = 5–7) salts were used as highly efficient catalysts, which is a novel tendency in chlorobismuthate researchs in the green chemistry field.
