The first proof of protonated anion tetrahedra in the tsumcorite-type compounds
Abstract
<jats:title>Abstract</jats:title><jats:p>Hydrothermal synthesis produced the new compound SrCo<jats:sub>2</jats:sub>(AsO<jats:sub>4</jats:sub>)(AsO<jats:sub>3</jats:sub>OH)(OH)(H<jats:sub>2</jats:sub>O). The compound belongs to the tsumcorite group (natural and synthetic compounds with the general formula <jats:italic>M</jats:italic>(1)<jats:italic>M</jats:italic>(2)<jats:sub>2</jats:sub>(<jats:italic>X</jats:italic>O<jats:sub>4</jats:sub>)<jats:sub>2</jats:sub>(H<jats:sub>2</jats:sub>O,OH)<jats:sub>2</jats:sub>; <jats:italic>M</jats:italic>(1)<jats:sup>1+,2+,3+</jats:sup> = Na, K, Rb, Ag, NH<jats:sub>4</jats:sub>, Ca, Pb, Bi, Tl; <jats:italic>M</jats:italic>(2)<jats:sup>2+,3+</jats:sup> = Al, Mn<jats:sup>3+</jats:sup>, Fe<jats:sup>3+</jats:sup>, Co, Ni, Cu, Zn; and <jats:italic>X</jats:italic><jats:sup>5+,6+</jats:sup> = P, As, V, S, Se, Mo). It represents (1) the first Sr member, (2) the until now unknown [7]-coordination for the <jats:italic>M</jats:italic>(1) position, (3) the first proof of (partially) protonated arsenate groups in this group of compounds, and (4) a new structure variant.</jats:p><jats:p>The crystal structure of the title compound was determined using single-crystal X-ray diffraction data. The compound is monoclinic, space group <jats:italic>P</jats:italic>2<jats:sub>1</jats:sub>/<jats:italic>a</jats:italic>, with <jats:italic>a</jats:italic> = 9.139(2), <jats:italic>b</jats:italic> = 12.829(3), <jats:italic>c</jats:italic> = 7.522(2) Å, β = 114.33(3)°, <jats:italic>V</jats:italic> = 803.6(3) Å<jats:sup>3</jats:sup>, <jats:italic>Z</jats:italic> = 4 [w<jats:italic>R</jats:italic>2 = 0.065 for 3530 unique reflections]. The hydrogen atoms were located experimentally.</jats:p>
