Trirubidium cobalt tetrachloride nitrate(V), Rb₃CoCl₄NO₃

R. Ouarsal, M. Lachkar, M. Bolte and B. El Bali

Abstract: The title compound, Rb₃CoCl₄NO₃, is isostructural with K₃ZnCl₄NO₃. It is built up from Rb⁺ cations, NO₃^- anions and [CoCl₄]^2- complex ions which form a layer-like arrangement: one layer contains only rubidium cations while the other contains a mixture of rubidium, nitrate and tetrachlorocobaltate ions. Both rubidium cations are ninefold coordinated by three O atoms and six Cl ions. One Rb atom, the Co atom, two Cl atoms, the N atom and one O atom lie on a crystallographic mirror plane.
