Rhodamine 6G hexa-chlorido-stannate(IV) acetonitrile disolvate

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 octa-hedral 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 - H⋯Cl hydrogen bonds between SnCl6 2- ions and rhodamine 6G cations as well as π-π stacking inter-actions between rhodamine 6G cations (inter-planar distance of 3.827 Å). © International Union of Crystallography 2008.
