Self assembling perovskite-type organic-inorganic hybrids have been the focus of a number of investigations in recent years. Combining the characteristics of the organic and inorganic components offers an opportunity to incorporate useful properties, and thus providing access to a vast area of complex, multifunctional materials. 1 Fascination with these materials is generated by their interesting structural, magnetic, electrical, optical and chemical properties.Compounds having the general formula (NH3(CH2)nNH3)MX4 with X = Br, Cl, I and M = metal are known to crystallize in a layer structure. 2 These hybrid materials can be classified into two groups, based on the nature of the interface between the organic and inorganic entities; in a first group organic and inorganic compounds are linked only by weak bonds (hydrogen or van der-Waals bonds), while in a second group the two entities are linked together through strong chemical (either covalent or ionic) bonds. It has been shown that the structure of the MX4 units can vary considerably, ranging from isolated molecules (0D) 3 to extended chains (1D) 4 and up to two 5 or three-dimensional 6 networks.In this article we report on a new 0-dimensional compound that contains alkyl-chain diammonium 1,8-diammoniumoctane (abbreviated DAO), [CoCl4] 2-(abbreviated TCC) tetrahedral and uncoordinated chloride ions, connected by hydrogen bonds. The crystal structure was determinated by X-ray diffraction (XRD).Crystals of the title compound suitable for single-crystal X-ray diffraction were prepared as follows: CoCl2·6H2O (0.36 g, 1.5 mmol) was dissolved in an aqueous solution of HCl (37%); 1,8-diaminooctane (0.22 g, 1.5 mmol) was dissolved in 10 ml of distilled water/ethanol (1:1 v/v). The two solutions were then Fig. 1 Asymmetric unit of DAOTCC, with atom labels and 50% probability displacement ellipsoids for non-H atoms.
