Abstract:
(SO4 )-rich silicate analogue borosulfates are able to stabilise cationic cluster-like and chain-like aggregates. Single crystals of [Au3 Cl4 ][B(S2 O7 )2 ] and [Au2 Cl4 ][B(S2 O7 )2 ](SO3 ) were obtained by solvothermal reaction with SO3 , and the electronic properties were investigated by means of density functional theory-based calculations. [Au3 Cl4 ][B(S2 O7 )2 ] exhibits a cluster-like cation, and the cationic gold-chloride strands in [Au2 Cl4 ][B(S2 O7 )2 ](SO3 ) are found to resemble one-dimensional metallic wires. This is confirmed by polarisation microscopy.

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
