Mr = 546.3, orthorhombic, space group Cmc21, a = 14.223(4), b = 12.907(3), c = 12.343(4) A, V = 2265.746 A3, Z = 4, DC = 1.601 Mg.m-3, λ= 0.7106 A, μ(MoK(?)) = 56.86 cm-1, F(OOO) = 1048. Final R = 0.044 for 1937 observed reflections. Cation [W(H)2(F)(OH2)(PMes)4]4 has a mirror symmetry, an equatorial belt of four PMe3 groups and mutually syn fluoride and water Ugands. The mean W-P length is 2.462 (A) and P-C 1.83 (A). From the dimensions of the metal, fluoride and water system ( W(1)-F(1) = 2.08(1), W(1)-0(1) - 2.084(9), F(2)-O(1) = 2.59(2) A and F(2)-W(1)-O(1) - 76.7(4)°) an in-terligand hydrogen bond was assumed. The ligand water molecule also makes an H-bonded contact with the fluoride counter ion.
