Tetrakis(benzylamino)phosphonium chloride

K. Gholivand, H. Mostaanzadeh and S. Farshadian

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-HCl interactions, forming parallel chains along the c axis.
