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

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

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.

Comment top

In the title molecule, (I), the geometry is intermediate between a square-base pyramid and a trigonal bipyramid (t = 0.41). The thione bond distance of 1.738 (3) Å is longer than in the uncoordinated precursor molecule [1.628 (2) Å; Arquero et al., 1998] andis intermediate between the theoretical C—S single and double bond lengths (Sutton, 1965), as occurs with N—N bonds. The X-ray analysis confirms the structure proposed from spectroscopy measurements.

Experimental top

The complex was synthesized as described by López-Torres et al. (2003). Recrystallization from chloroform afforded colourless crystal suitable for X-ray analysis.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
