N2  - Tin(II) xanthates form adducts with donor molecules and react with excess xanthate to form the tris-xanthato ion, Sn(EtOCS2)3-. No such reactions are observed with tin(IV) xanthates. Reaction of quinolin-8- ol with tin(IV) ethylxanthate results in the replacement of two xanthate moieties by two oxinato ions.     The crystal structure of [Sn(EtOCS2)4] has been determined by single-crystal X-ray diffraction at 295 K and refined by least squares to a residual of 0.038 for 2378 'observed' reflections. The tin(IV) coordination environment resembles that observed in the N,N- diethyldithiocarbamate analogue, two of the xanthate ligands being monodentate and coordinating cis [Sn-S, 2.488(2), 2.499(2) &#506;] in the six-coordinate coordination sphere while the other two ligands are bidentate, the Sn-S distances trans to the monodentate ligands being slightly longer [2.617(2), 2.627(2)&#506;] than the other two [2.562(2), 2.539(2)&#506;]. Crystals are monoclinic, P21/c, a 10.341(5), b 10.465(4), c 21.88(1) &#506;, &#946; 98.36(4)&#176;, Z 4.
