Crystal data for a new molecular addition compound, triphenyllead(IV) chloride–hexamethylphosphoramide

Colourless crystals of (C₆H₅)₃PbCl.[(CH₃)₂N]₃PO have been grown by mixing the two components in acetone solution, in which the complex is monomeric. They were recrystallized from acetone or benzene. Precession and Weissenberg photographs yield space group P2₁/n and cell data, at 20°C: a = 18.35 (6), b = 15.62 (5), c = 9.43 (5) Å, β = 93°30′ (10′), Z = 4. D_m = 1.50 (2), 20°C.
