In the title compound, (C(28)H(43)N(2))[SnCl(3)], two pairs of molecular species are present in the asymmetric unit. The employed α-diimine opens up, forming a highly asymmetric ammonium that has its protons at one of the N atoms [N-C= 1.264 (4) and 1.516 (4) Å]. One of the C=N double bonds was oxidized to C-N, which is consistent with the bond length of 1.516 (4) Å. Meanwhile Sn(IV) was reduced to Sn(II). The (SnCl)(3) (-) anion is trigonal-pyramidal. In the crystal, mol-ecules are linked by C-H⋯Cl, N-H⋯Cl, N-H⋯N and C-H⋯N bonds. The crystal studied was twinned by pseudo-merohedry.
