Abstrakt: Summary. Hydrazinium(+2) fluoroarsenate(III) fluoride was prepared by the reaction of hydrazinium(+2) fluoride and liquid arsenic trifluoride. N2H6AsF4F is stable at 273 K, but decomposes slowly at room temperature. N2H6AsF4F crystallizes in the orthorhombic space group Pnn2 with a = 774.0(2) pm, b = 1629.2(4) pm and c = 436.6(1) pm; V = 0.5506(3) nm3, Z = 4 and dc = 2.461 g cm-3. The structure consists of N2H62+ cations, AsF4- anions, and F- anions and is interconnected by a hydrogen bonding network. Distorted trigonal-bipyramidal AsF4- units are very weakly interconnected and form chains along the b axis. Bands in the Raman spectrum are assigned to the vibrations of N2H6+2 cations and AsF4- anions. [ABSTRACT FROM AUTHOR]
