摘要
[Ph4P]2[Pb3Br8] and [Ph4As]2[Pb3Br8] crystallize both in the monoclinic space group P 21/n. The lattice parameters of [Ph4P]2[Pb3Br8] are a = 14.637(7), b = 8.151(3), c = 23.388(8) Å, β = 106.02(3)°, Z = 2 and of [Ph4As]2[Pb3Br8] are a = 14.697(7), b = 8.219(3), c = 23.527(8) Å, β = 106.27(3)°, Z = 2. The lattice parameters of [Ph4P][PbBrCl2]·CH3CN, which crystallizes in the triclinic space group (P 1¯), are a = 9.435(3), b = 10.2577(14), c = 14.055(2) Å, α = 88.320(11)°, β = 84.82(2)°, γ = 84.19(2)°, Z = 2. 207Pb NMR shifts of halogenoplumbates in solution are reported.
