Extraction of Free Brucite from Brucite-containing Serpentine by Bicarbonation.

Inter­calated brucite-type layered cobalt(II) hydroxy­sulfate

In an attempt to synthesize new cobalt(II) sulfate framework structures using 1,4-diaza-bicyclo-[2.2.2]octane as a template, crystals of poly[0.35-[hexa-aqua-cobalt(II)] [tri-μ-hydroxido-μ-sulfato-dicobalt(II)]], {[Co(H(2)O)(6)](0.35)[Co(2)(OH)(3)(SO(4))]}(n), were obtained as a mixture with [Co(H(2)O)(6)]SO(4) crystals. The crystal structure can be described as being constructed from discrete ...

Spectral Evidence for a Brucite-carbonate Alteration Assemblage on Ceres

Introduction: The dwarf planet Ceres is the largest object in the asteroid belt and is a primary target of NASA’s Dawn mission [1]. Recent modeling has shown that Ceres is likely differentiated and consists of a thin silicate+ice crust underlain by a thicker water ice mantle [2,3]. The presence of hydrated phases on Ceres, as inferred from the 3 μm absorption feature present in surface reflecta...

On the Formation of Brucite and Cronstedtite on Ceres

Structure and magnetism of new hybrid cobalt hydroxide materials built from decorated brucite layers.

The structure, synthesis and magnetic properties of three new complex cobalt hydroxyl oxalates are presented, showing a modification of the 2-D double layer hydroxide structure. Co(12)(OH)(18)(ox)(3)(pip) [ox = oxalate, C(2)O(4)(2-); pip = piperazine, C(4)N(2)H(10)] (1), is essentially built from brucite-like layers with a one ninth depletion of the octahedral sites and a preservation of a trig...
