N2 - The reaction of SnCl4 with squaric acid in methanol yields colorless crystals of [(n- C4H9)4N]2[Sn2Cl4(OCH3)2(C4O4)2]. The compound crystallizes in the monoclinic space group P21/c with a = 13.914(2), b = 10.858(3), c = 19.305(4) Å, β = 112.49(1)°, V = 2694.8(12) Å3, Z = 2, Dcalc = 1.42 g cm-3. Structure solution and refinement based on 2120 reflections with F0≥6σ(F0) (Mo Kα radiation, λ = 0.71073 Å, 3529 reflections collected) converged at a conventional discrepancy value of 0.069. The structure consists of discrete (n-C4H9)4N+ cations and [Sn2Cl4(OCH3)2(C4O4)2]2- anions. The methoxy groups and the squarate ligands adopt bridging coordination to the hexacoordinate Sn(IV) centers.
