title: Hydrogen Polyphosphides P3H2(3-) and P3H3(2-): synthesis and crystal structure of K3(P3H2).2.3NH3, Rb3(P3H2).NH3, [Rb(18-crown-6)]2(P3H3).7.5NH3, and [Cs(18-crown-6)]2(P3H3).7NH3.
abstract: The incongruous solvation of polyphosphides and phosphanes or the direct reduction of white phosphorus in liquid ammonia leads to the hydrogen polyphosphides catena-dihydrogen triphosphide, P(3)H(2)(3-), and catena-trihydrogen triphosphide, P(3)H(3)(2-), in the crystalline compounds K(3)(P(3)H(2)).2.3NH(3) (1), Rb(3)(P(3)H(2)).NH(3) (2), [Rb(18-crown-6)](2)(P(3)H(3)).7.5NH(3) (3), and [Cs(18-crown-6)](2)(P(3)H(3)).7NH(3) (4).
