The structures of tris(2-aminobenzyl)amine, C21H24N4, (I), and methyltris[2-(triethoxyphosphoranylidene-amino)benzyl]ammonium tetrafluoroborate, C40H66N4O9P3+. BF4-, (II), have been determined at room temperature and at 150 K, respectively. To our knowledge, this is the first time that a tris(phosphiteimine) compound such as (II) has been described. In (I), all NH2 groups are involved in weak N-H ... N intramolecular hydrogen bonding: two of them act as both donor and acceptor and are responsible for the formation of chains along the a axis.
