Abstract:
The structure of the title compound, C(16)H(40)N(4)P(+).Br(-).0. 5H(2)O or [P¿N(C(2)H(5))(2)¿(4)]Br.0.5H(2)O, at 130 K has Z' = 4 and is ionic, with Br not bonded to P. The P atoms are tetrahedral, with P-N distances in the range 1.628 (2)-1.6400 (19) A. The N atoms are approximately planar. The water molecules form cyclic hydrogen-bonded [(H(2)O)(2)Br(2)](2-) units about inversion centers, with O.Br distances in the range 3.425 (2)-3.611 (3) A.
