Chloro[5,6-diphenyl-1,2,4-triazine-3(2H)-thionato]dimethyltin(IV)

E. López-Torres, M. A. Mendiola and C. J. Pastor

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.
