AbstractHydrothermal synthesis produced the new compound SrCo2(AsO4)(AsO3OH)(OH)(H2O). The compound belongs to the tsumcorite group (natural and synthetic compounds with the general formula M(1)M(2)2(XO4)2(H2O,OH)2; M(1)1+,2+,3+ = Na, K, Rb, Ag, NH4, Ca, Pb, Bi, Tl; M(2)2+,3+ = Al, Mn3+, Fe3+, Co, Ni, Cu, Zn; and X5+,6+ = P, As, V, S, Se, Mo). It represents (1) the first Sr member, (2) the until now unknown [7]-coordination for the M(1) position, (3) the first proof of (partially) protonated arsenate groups in this group of compounds, and (4) a new structure variant.The crystal structure of the title compound was determined using single-crystal X-ray diffraction data. The compound is monoclinic, space group P21/a, with a = 9.139(2), b = 12.829(3), c = 7.522(2) Å, β = 114.33(3)°, V = 803.6(3) Å3, Z = 4 [wR2 = 0.065 for 3530 unique reflections]. The hydrogen atoms were located experimentally.

A new Lindqvist polyoxometalate-based hybrid compound with a helical chain structure, [Cu(bipy)2][W6O19] (1), (bipy = 2;20`-bipyridine), has been hydrothermally synthesized and characterized by elemental analysis, infrared spectroscopy, thermogravimetry, and single-crystal X-ray diffraction. The compound crystallizes in the space group C2/c of the monoclinic system. In 1, the [W6O19]2- anions are connected alternately with [Cu(bipy)2]2+ subunits to form a meso-helical chain. To our knowledge, this structure represents the first example of a helical chain structure consisting of the hexatungstate anion [W6O19]2-. The electrochemical properties of the title compound have been studied.

A polyoxometalate-based copper(II) inorganic-organic hybrid polymer [Cu(dpdo)2(H2O)4] [Na2(Mo8O26) (H2O)6] (dpdo) 2H2O (1) (dpdo=4,4’-bipyridine-N,N'-dioxide) has been synthesized and structurally characterized by IR spectroscopy, elemental analysis, and single-crystal X-ray analysis. The structure is based on two types of polymeric chains, the anionic one constructed by the coordination interaction between the [b-Mo8O26]4- cluster anions and [Na2]2+ units, and the cationic one formed through the coordination interaction of Cu(II) atoms and dpdo ligands. In addition, there are multiform hydrogen bonds and π … π interactions in a three-dimensional supramolecular network
