title: Tetra-kis(benzyl-amino)-phospho-nium chloride.
abstract: The title salt, [P(NHCH(2)C(6)H(5))(4)](+)·Cl(-), crystallizes with the P atom and Cl(-) anion lying on a twofold rotation axis. The P atom has a slightly distorted tetra-hedral 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 sp(2)-hybridized N atoms are essentially planar (sum of angles = 359.9 and 360.1°). In the crystal, the phospho-nium ion inter-acts with each neighboring chloride ion via two approximately equal N-H⋯Cl inter-actions, forming parallel chains along the c axis.
