Abstract: The reaction between dichlorodimethyltin(IV) and 5-methoxy-5,6-diphenyl-4,5-dihydro-2H-1,2,4-triazine-3-thione yields the title complex, [SnClMe₂(C₁₅H₁₀N₃S)]. The coordination sphere of the Sn atom is formed by the S, amine N and Cl atoms and two methyl groups, giving a pentacoordinate geometry. The distances Sn-N  =  2.525  (2)  Å, Sn-S  = 2.4671  (7)  Å, Sn-C  =  2.109  (3) and 2.111  (4)  Å, and Sn-Cl  =  2.4220  (7)  Å are in the ranges expected for this type of complex. The coordination mode of the triazinethione ligand results in a four-membered chelate ring.
