Abstract: The asymmetric unit of the unexpected title compound, 2,2,6,6-tetra-n-butyl-2,6-dichloro-4,8-bis{[(1E)-4-methoxybenzylidene]hydrazino}-1,5-diaza-2,6-distanna-3,7-dithiabicyclo[3.3.0]octa-3,7-diene bis{1,5[(1E)-4-methoxybenzylidene]thiocarbonohydrazide} ethanol disolvate, [Sn₂(C₄H₉)₄Cl₂(C₁₈H₁₈N₆O₂S₂)]·2C₁₇H₁₈N₄O₂S·2C₂H₅OH, comprises one half-molecule of the organotin complex, one thiocarbonohydrazide molecule and one ethanol solvent molecule, and is the first example of a substituted C₂N₂S₂Sn₂ planar dicyclo-organotin complex. Each Sn^IV atom is pentacoordinated with a distorted trigonal-bipyramidal geometry and the complex is disposed across a crystallographic centre of inversion. Weak intermolecular N-HCl and C-HCl hydrogen bonds and weak SS interactions link the molecules of the organotin complex into one-dimensional infinite chains.
