Abstract
[Ph4P](2)[Pb3Br8] and [Ph4As](2)[Pb3Br8] crystallize both in the monoclinic space group P 2(1)/n. The lattice parameters of [Ph4P](2)[Pb3Br8] are a = 14.637(7), b = 8.151(3), c = 23.388(8) Angstrom, beta = 106.02(3)degrees, Z = 2 and of [Ph4As](2) [Pb3Br8] are a = 14.697(7), b = 8.219(3), c = 23.527 (8) Angstrom, beta = 106.27(3)degrees, Z = 2. The lattice parameters of [Ph 4P][PbBrCl2]. CH3CN, which crystallizes in the triclinic space group (P (1) over bar), are a = 9.435(3), b = 10.2577(14), c = 14.055(2) Angstrom, alph a = 88.320(11)degrees, P = 84.82(2)degrees, gamma = 84.19(2)degrees, Z = 2. Pb-207 NMR shifts of halogenoplumbates in solution are reported.
