Z. Naturforsch.56 b,301–305 (2001); received January 11, 2001 Arsenic, Chlorooxoarsenate(III), NBO Analysis

[NMe4]2[As4O2Cl10]2CH3CN was recovered by the reaction of [NMe4][N3] with AsCl3in CH3CN under aerobic conditions. This compound was also obtained directly by the reaction of AsCl3, As2O3 and [NMe4][Cl] in acetonitrile. The structure was determined by X-ray diffraction. [NMe4]2[As4O2Cl10] 2 CH3CN crystallizes in the orthorhombic 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 [As4O2Cl10]2 anion in comparison with computational results. The bonding situation in the [As4O2Cl10]2 anion was elucidated on the basis of an NBO analysis on the crystallographic data.
