摘要

When a benzene solution of tBu _2PHO·BCl _3 was exposed to air at room temperature, the phosphonium chloride [tBu _2PH _2]Cl was formed together with di-tert-butylphosphinic acid, tBu _2PO(OH). X-ray quality crystals of the hydrochloride [tBu _2PH _2]Cl·HCl were obtained from the reaction solution at room temperature. The hydrochloride [tBu _2PH _2]Cl·HCl crystallizes in the monoclinic space group P2 _1/m, a = 6.3012(7) ?, b = 6.8970(10) ?, c = 14.5011(15) ?, β = 99.376(9)°, V = 621.79(13) ? ~3, Z = 2, d _(calcd) = g cm- ~3 1.165; R1 = 0.0510, wR2 = 0.1503 for 1,129 reflections with I > 2σ(I). The crystal was a non-merohedral twin with a contribution of 0.353(7) of the minor component. The structure is composed of discrete di-t-butylphosphonium cations and Cl anions. Both are located on a crystallographic mirror plane and are connected by P-H...Cl hydrogen bonds.
