Catena-Poly[[[dichlorido(pyridin-1-ium-3-yl)arsenic(III)]-?-chlorido] mono-hydrate].


ABSTRACT: The crystal structure of the title compound, {[AsCl3(C5H5N)]·H2O} n , is characterized by polymeric chains consisting of alternating arsenic and chlorine atoms running parallel to the a axis. O-H?Cl and N-H?O hydrogen bonds mediated by non-coordinating water mol-ecules assemble these chains into a three-dimensional framework. The As(III) atom, the atoms of the pyridinium ring and the water O atom have m site symmetry and the bridging Cl atom has site symmetry 2. This is the first reported organotrichloro-arsenate(III) in which arsenic adopts a ?-octa-hedral fivefold coordination.
