The crystal structure of the title compound, [Sn(S2COEt)2(C9H6NO)2], has been determined by single-crystal X-ray diffraction at 298 K and refined by least squares to a residual of 0·049 for 1771 ‘observed’ reflections. Crystals are monoclinic, P21/n, a 12·21(1), b 24·33(1), c 9·159(7) Å, β 102·12(6)°, Z 4. The environment of the tin atom is six-coordinate: the two coordinating sulfur atoms of the monodentate xanthate ligands lie cis in the coordination sphere [Sn-S, 2·484(4), 2·510(4) Å], and one in turn trans to the two oxine nitrogen atoms [Sn-N, 2·260(8), 2·237(10) Å]. The remaining positions, trans to each other, are occupied by the oxine oxygen atoms [Sn-O, 2·047(7), 2·065(8) Å]. O-Sn-O is 157·0(3)°. The overall point symmetry of the molecule is a good approximation to 2.
