...Alexandra Friedrich; Fiorenzo Mazzi; Manfred Wildner; Ekkehart Tillmanns Abstract Isotypism of synthetic Co(H 2 O) 6 [Sb(OH) 6 ] 2 with brandholzite, Mg(H 2 O) 6 [Sb(OH) 6 ] 2 , and bottinoite, Ni(H 2 O) 6 [Sb(OH) 6 ] 2 , is obtained by an origin shift of the unit cell of Co(H 2 O) 6 [Sb(OH) 6 ] 2...

...Paola Bonazzi; Fiorenzo Mazzi Abstract The crystal structure of bottinoite, Ni(H 2 O) 6 [Sb(OH) 6 ] 2 , was determined from a twinned crystal. This study revealed that the strong 3 1 m pseudosymmetry shown by all the natural and synthetic crystals examined results from {10 1 0} twinning...

...Paola Bonazzi; Silvio Menchetti; Andrea Caneschi; Stefano Magnanelli Abstract Bottinoite, a new nickel and antimony hydrated hydroxide mineral, occurs at the Bottino mine, Alpi Apuane, Italy. Associated minerals are ullmannite, siderite, calcite, quartz, phlogopite, pyrite, chalcopyrite...

...Fig. 4 The refined percentages (by single-crystal X-ray diffraction) of tredouxite (with respect to bottinoite) for three different crystals plotted against the analytical totals measured by electron micro-probe on the same crystal fragments. Ideal bottinoite and tredouxite values are also...

...( F o ) (synthetic analogue) and 525 variable parameters each. The structures are isotypic with bottinoite, Ni(H 2 O) 6 [Sb(OH) 6 ] 2 , and are built up by nearly regularly shaped, isolated Mg(H 2 O) 6 and Sb(OH) 6 octahedra which are interconnected by hydrogen bonds only. The strongest lines...

.... , 1941 ; Ercit et al. , 2002 ). The Zn analogue of brandholzite has never been reported to occur naturally, although the Ni 2+ analogue, bottinoite, is well known. Solubility data for both brandholzite and bottinoite were determined by Deimar et al. (2009), who concluded that the minerals...

... by Bonazzi and Mazzi (1996) and Friedrich et al. (2000) in their structural studies of bottinoite and brandholzite, respectively. The refinement of the new model was carried out in both space groups P 3̅ and P 3; however, no significant improvement was obtained for the lower symmetry model...

... at the Correc d'en Llinassos, no Ni-bearing secondary minerals other than annabergite had been reported. A field trip to look for other Ni-bearing secondary minerals resulted in the discovery of the first French bottinoite, glaukosphaerite and the first specimens of a new Ni-, Cu-, Fe-, and Sb-bearing hydroxide...

... it unlikely that any of its ligands are water molecules, which have very low Lewis acidity. Instead, they are probably hydroxide anions, making the well-known [Sb(OH) 6 ] − anion that is found in minerals such as mopungite, Na[Sb(OH) 6 ] ( Williams, 1985 ), bottinoite, [Ni(H 2 O) 6 ][Sb(OH) 6 ] 2 ( Bonazzi...

... in a Ni-rich hydroxysilicate (likely willemseite) matrix, and it probably formed at temperatures around 600 °C, by impregnation of pervasive H 2 O-rich fluids, forming secondary hydrated minerals like bottinoite. It forms subhedral to anhedral grains varying in size from 10 to 500 μm, commonly intergrown...

... deposit caught the attention of two of the authors (GF + CB) due to the relative abundance of ullmannite, occurring in a weathered environment. The first search for Ni secondary minerals yielded the first French occurrence of bottinoite and a bright yellow mineral which turned out to be a new species...

... common sulfides and sulfosalts (chalcopyrite, jamesonite, pyrite, pyrrhotite, sphalerite, stibnite), together with products of their alteration (bindheimite, bottinoite, cerussite, erythrite, gypsum, hydrozincite, sulfur) and with other common phases (“apatite”, barite, “chlorite”). In the veins...
