Bottom Line: The central C atom is bonded to the three N atoms in a nearly ideal trigonal-planar geometry and the positive charge is delocalized in the CN(3) plane.The bonds between the N atoms and the terminal C-methyl groups of the guanidinium moiety, all have values close to a typical single bond [1.4630 (16)-1.4697 (17) Å].The phenyl rings form a kind of aromatic pocket, in which the guanidinium ion is embedded.

ABSTRACT
In the crystal structure of the title salt, C(12)H(30)N(4) (2+)·2C(24)H(20)B(-), the C-N bond lengths in the central CN(3) unit of the guanidinium ion are 1.3388 (17), 1.3390 (16) and 1.3540 (17) Å, indicating partial double-bond character in each. The central C atom is bonded to the three N atoms in a nearly ideal trigonal-planar geometry and the positive charge is delocalized in the CN(3) plane. The bonds between the N atoms and the terminal C-methyl groups of the guanidinium moiety, all have values close to a typical single bond [1.4630 (16)-1.4697 (17) Å]. C-H⋯π inter-actions are present between the guanidinium H atoms and the phenyl C atoms of one tetra-phenyl-borate ion. The phenyl rings form a kind of aromatic pocket, in which the guanidinium ion is embedded.
