The crystal structures of complex antimony(III) fluorides RbSbF4 (I) and (C2N4H5)SbF4 (II) were determined. The crystals of I and II are monoclinic; for I: a = 4.628(1) Angstrom, b = 6.167(1) Angstrom, c = 7.922(1) Angstrom, beta = 100.582(3)degrees, V = 222.24(7) Angstrom(3), Z = 2, rho(calcd.) = 4.23 g/cm(3), rho(exp.) = 4.25 g/cm(3), F(000) = 248, space group P2(1)/m, R = 0.0395; for II: a = 4.678(1) Angstrom, b = 7.339(4) Angstrom, c = 10.185(1) Angstrom, beta = 90.88(2)degrees, V = 349.6(2) Angstrom(3), Z = 2, rho(calcd.) = 2.69 g/cm(3), rho(exp.) = 2.70 g/cm(3), F(000) = 264, space group P2(1). The structure of I is formed by Rb+ cations and [SbF4](n)(n-) anionic chains composed of SbF5E octahedra with two bridging fluorine atoms. The structure of II is formed by (C2N4H5)(+) cations and isolated [SbF4](-) anions in which the antimony polyhedra are SbF4E trigonal bipyramids. The relationship between the crystal structures and electrophysical and biological properties of single-charged cation tetrafluoroantimonates(III) was studied.
