Tetrakis(benzylamino)phosphonium chloride

Abstract

The title salt, [P(NHCH2C6H5)4]+·Cl−, crystallizes with the P atom and Cl− anion lying on a twofold rotation axis. The P atom has a slightly distorted tetrahedral geometry with two classes of N—P—N angles [101.15 (10) and 100.55 (11)° and 113.07 (9) and 114.83 (8)°] and the environments of sp2-hybridized N atoms are essentially planar (sum of angles = 359.9 and 360.1°). In the crystal, the phosphonium ion interacts with each neighboring chloride ion via two approximately equal N—H...Cl interactions, forming parallel chains along the c axis.
