ChemInform Abstract: Missing Links in the Sulfate Chemistry of Group 15 Elements: As(S₂O₇)(HS₂O₇), Sb₂(SO₄)₂(S₂O₇) and Bi₂(S₂O₇)₃ from Reactions in Oleum under Harsh Conditions.

Abstract

evacuated glass tubes, 150°C fo (I), 250°C for (II) and (III), 24 h). (I), (II), and (III) crystallize in the monoclinic space group P2 1 /c (Z = 4), P2 1 /n (Z = 4), and the triclinic space group P1 (Z = 2, single crystal XRD), respectively. (I) shows the As atoms in a trigonal pyramidal coordination of O atoms of one chelating S2 and one monodentate HS2 group. Hydrogen bonding in (I) results in layers. (II) shows the Sb 3+ cations in a seesaw-type coordination of O from both anions. In (III) the Bi 3+ cations are in a square prismatic O coordination of disulfate units. Linkages in (II) and (III) result in complex three-dimensional structures. -(LOGEMANN, C.; KLEINEBERG, H.; OHLERT, J.; WICKLEDER*, M. S.; Z. Anorg. Allg. Chem. 639 (2013) 15, 2796-2803, http://dx.
