ABSTRACT: In the title salt, C11H27N4 (+)·C24H20B(-), the C-N bond lengths in the central CN3 unit of the guanidinium ion are 1.333 (4), 1.334 (4) and 1.351 (4) Å, indicating partial double-bond character. The C atom of this unit is bonded to the three N atoms in a nearly ideal trigonal-planar geometry [N-C-N angles = 118.8 (3), 120.0 (3) and 121.2 (3)°] and the positive charge is delocalized in the CN3 plane. The bonds between the N atoms and the terminal C-methyl groups of the guanidinium moiety have values in the range 1.459 (4)-1.478 (4) Å, close to a typical single bond. In the crystal, there are C-H⋯π inter-actions between the guanidinium H atoms and the phenyl rings of the tetra-phenyl-borate ion. These inter-actions combine to form a ladder of linked chains of ions which runs parallel to the
