N-(2,6-Diisopropyl­phen­yl)-N-{3-[(2,6-diisopropyl­phen­yl)imino]­butan-2-yl}aza­nide trichloridostannate(II)

In the title compound, (C₂₈H₄₃N₂)[SnCl₃], 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, mol­ecules 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.
