Abstract: In the title compound, bis({6-ethylamino-10-[2-(methoxycarbonyl)phenyl]-2,7-dimethylxanthen-3-ylidene}ethanaminium) hexachloridotin(IV) acetonitrile disolvate, (C₂₇H₂₉N₂O₃)₂[SnCl₆]·2C₂H₃N, the octahedral SnCl₆^2- anion lies on an inversion center. The xanthene ring system is essentially planar, with an average deviation of 0.020 Å, and the substituent benzene ring forms a dihedral angle of 85.89 (2)° with it. The Sn-Cl distances are in the range 2.4237 (3)-2.4454 (3) Å. There are N-HCl hydrogen bonds between SnCl₆^2- ions and rhodamine 6G cations as well as - stacking interactions between rhodamine 6G cations (interplanar distance of 3.827 Å).
