A new organic–inorganic compound, ethylenediammonium hexachloridostannate(IV) p-anisaldehyde disolvate

Abstract

The asymmetric unit of the title organic–inorganic hybrid complex [systematic name: ethane-1,2-diaminium hexachloridostannate(IV)–4-methoxybenzaldehyde (1/2)], (C2H10N2)[SnCl6]·2C8H8O2, contains one half of an ethylenediammonium cation, one half of an [SnCl6]2− anion and one p-anisaldehyde molecule. Both the organic cation and the quasi-regular octahedral inorganic anion are located about inversion centres. The organic cations and [SnCl6]2− anions lie in layers parallel to the ac plane with p-anisaldehyde molecules occupying the space between the layers. A network of classical N—H...Cl and N—H...O hydrogen bonds exists between the ethylenediammonium cations and the [SnCl6]2− anions and p-anisaldehyde molecules. These interactions, together with non-classical C—H...O interactions between the ethylenediammonium cations and the p-anisaldehyde molecules, serve to hold the structure together. The crystal studied was refined as a two-component twin.
