Abstract.[Sn(C4H9)2(C7HI4NS2)2], Mr=585.6, triclinic, Pi, a=9.7836(7), b= 12.3437(6), c= 13.2950 (8) 0108-2701/92/040627-03503.00 chelated to tin(IV), with one longer and one shorter Sn--S bond. The overall geometry at the Sn atom is highly distorted from trans octahedral. Four S atoms are nearly coplanar but are greatly distorted from square-planar geometry (cis S--Sn--S angles range from 63.9 to 148.6°).Introduction. Crystallographic studies of organotin dithiocarbamato complexes have revealed a variety of coordination geometries around the Sn atom. © 1992 International Union of Crystallography 628[Sn(C4H9)2(C7H14NS2)2] Thus, bis(N,N-diethyldithiocarbamato)diphenylstannane (Lindley & Carr, 1974) contains two bidentate dithiocarbamato groups giving rise to a distorted cis-octahedral geometry around the Sn atom, whereas in (dimethyldithiocarbamato)trimethylstannane Sheldrick, Sheldrick, Dalton & Jones, 1970) and in bis(diethyldithiocarbamato)dimethylstannane (Lockhart, Manders, Schlemper & Zuckerman, 1986) coordination numbers of the Sn atoms are five and six, respectively.In this paper we report the structure of [(n-Bu)ESn(S:CNPr2)2]. One aim of this work was to make a contribution to understanding the metalligand bonds in organotin dtc complexes.Experimental. Colourless crystals of the title compound were prepared by dissolution of the sodium salt of dipropyldithiocarbamic acid in ethanol and adding ethanol solution of the chloride of tin dibutylene. The product was recrystaUized from chloroform--ethanol. Elemental analysis found: N, 4.81; C, 45.19; S, 21.98; H, 7.96%. Calculated for C22H46N284Sn • N, 4.78; C, 45.12; S, 21.90; H, 7.96%. To obtain the intensity data a crystal 0.2 x 0.1 × 0.3 mm was chosen. Density measured by flotation in ZnSO4 solution. 24 reflections (14 < 20 < 26 °) were used for measuring lattice parameters; maximum sin0/a = 0.765 A-l; intensities (h = 0 to 13, k = -18 to 18, l = -20 to 20) measured on a Hilger & Watts Y/290 diffractometer with Mo Ka radiation; graphite monochromator, w/20 scan. Three standards measured every 100 reflections showed +__ 2% intensity variation; corrections for Lorentz and polarization effects, but not for absorption. 6089 reflections measured, 5055 unique, and 5055 reflections with I_> 2.0tr(/) considered observed and used for structure determination. Structure solved by the heavy-atom method; full-matrix least-squares refinement on F; H atoms located in difference electron density map [except H atoms of the butyl group C(19)-C (22) Discussion.

The crystal and molecular structure of SnBu2(pmdtc)2 has been solved by X-ray diffraction methods and refined by a block-diagonal least-squares procedure to R = 0.083 for 895 observed reflections. Monoclinic, space group C2, a = 19.893(6), b = 7.773(8), c = 12.947(8) . 10-10 m, β = 129.07(5)°, Z = 2, C20H38N2S4Sn. Measured and calculated densities are Dm = 1.38(2), Dc = 1.36 Mg m-3. Sn atom, placed on the twofold axes, is coordinated with four S atoms in the distances Sn-S 2.966(6) and 2.476(3) . 10-10 m. Coordination polyhedron is a strongly distorted octahedron. Ligand S2CN is planar.
The preparation of dibutyltin and tributyltin alkanedisulfonates from alkyltin oxides and the corresponding alkanedisulfonic acids has been studied. The products, obtained in 56 – 74% yield, were tested as biocides against bacteria, yeasts, and moulds as well as fungicides against wood rot and their activity was compared with that of bis(tributyltin) oxide.
