Low-temperature redetermination of hexa-kis(μ-chloro-acetato-κO:O')-μ(3)-oxido-tris[aquachromium(III)] nitrate 3.5-hydrate.
A low-temperature redetermination of the trinuclear cluster compound described as [Cr(3)(C(2)H(2)ClO(2))(6)O(H(2)O)(3)]NO(3)·3H(2)O [Glowiak, Kubiak & Jezowska-Trzebiatowska (1977 ▶). Bull. Acad. Pol. Sci. Ser. Sci. Chim.25, 359-371] shows that the salt is a 3.5-hydrate, [Cr(3)(C(2)H(2)ClO(2))(6...

Pol. Sci. Ser. Sci. Chim.25, 359-371] shows that the salt is a 3.5-hydrate, [Cr(3)(C(2)H(2)ClO(2))(6)O(H(2)O)(3)]NO(3)·3.5H(2)O. The trinuclear cluster cation is disordered in four of the six monochloro-acetate groups.
