Arsenic, Chlorooxoarsenate(III), NBO Analysis [NMe4 ]2 [As4 0 2 Clio] • 2 CH3CN was recovered by the reaction of [NMe4][N3] with AsCh in CH3CN under aerobic conditions. This compound was also obtained directly by the reaction of AsCb, AS2O3 and [NMe4][Cl] in acetonitrile. The structure was determined by X-ray diffraction. [NMe4 ]2 [As4 0 2Clio] • 2 CH3CN crystallizes in theoorthorhombic space group Fmmm with a = 11.4144(8), b = 14.732(1) and c = 19.803(2) A, with 4 formula units per unit cell. The frequencies obtained by Raman and infrared spectroscopy were assigned to the normal modes of the [As4 0 2 Cliol2~ anion in comparison with computational results. The bonding situation in the [As4 0 2 C1io]'~ anion was elucidated on the basis of an NBO analysis on the crystallographic data.

2012) Solvent effect on condensation of pyramidal [AsSe 3 ] 3-: solvothermal syntheses of new selenidoarsenates containing transition metal(II) complexes with 1,10-phenanthroline, Journal of Coordination Chemistry, 65:18, 3316-3328, The reactions As 2 O 3 , Se and 1,10-phenanthroline (phen) with NiCl 2 and ZnCl 2 in water at 140 C for 5 days afforded selenidoarsenates [Ni(phen) 3 ] 2 [As 8 Se 14 ] (1) and [Zn(phen) 3 ] 2 [As 8 Se 14 ] (2), respectively. The reactions with CoCl 2 and NiCl 2 in CH 3 OH aqueous solution produced polyselenidoarsenates [Co(phen) 3 ][As 2 Se 6 ] (3) and [Ni(phen) 3 ][As 2 Se 6 ] (4). All transition metal ions are octahedrally coordinated by six nitrogen atoms and all arsenics are trigonal pyramidally coordinated by three seleniums. In 1 and 2, eight [AsSe 3 ] 3À trigonal pyramids joined via edge-sharing to form [As 8 Se 14 ] 4À with condensation grade of 0.571. [As 8 Se 14 ] 4À contains two As 3 Se 3 and one As 6 Se 6 heterocycles. The formations of the selenidoarsenate anion [As 8 Se 14 ] 4À in 1 and 2 and polyselenidoarsenate [As 2 Se 6 ] 2À in 3 and 4 show solvent effect on condensation of trigonal bipyramidal [AsSe 3 ] 3À units under solvothermal conditions.

“…Focusing on selenoarsenates, a wide variety of isolated [As x Se y ] n− anions have been reported with diverse connectivity patterns of arsenic and selenium atoms as well as with various formal oxidation states of arsenic [4]. These anions include the selenium-rich species [AsSe 3 ] 3− [5,6], [AsSe 4 ] 3− [7 -10], [AsSe 6 ] − [11,12] [26], the structures of which are of cluster or cage type. In most cases the anions are charge-balanced by alkali/alkaline earth metal cations, but organoelement cations or transition metal complex cations were also employed.…”

Two novel selenoarsenates, K 3 AsSe 4 and K 4 As 2 Se 5 , were synthesized by the mild solvothermal reaction of potassium carbonate and arsenic and selenium powder in the presence of superheated ethylenediamine and structurally characterized by single-crystal X-ray diffraction. K 3 AsSe 4 crystallizes in the orthorhombic space group Pnma (no. 62) with a = 9.4169(4), b = 10.9695(5), c = 9.7568(8)Å, Z = 4 and V = 1007.86(10)Å 3 and contains [AsSe 4 ] 3− anions with pentavalent arsenic. K 4 As 2 Se 5 crystallizes in the monoclinic space group P2 1 /n (no. 14) with a = 7.6167(2), b = 22.8733(4), c = 8.4687(2)Å, β = 107.241(2) • , Z = 4 and V = 1409.14(5)Å 3 , and shows isolated [As 2 Se 5 ] 4− anions. The most prominent feature of the latter anions is the presence of arsenic in two different formal oxidation states (+4/ + 2) due to the presence of an As-As bond.
