Abstract

The structures of five tin(IV) complexes have been determined from film data (Cu radiation). In compounds (1)–(4), [Sn2X6(OH)2(OH2)2].nL, Lewis-base molecules L are hydrogen-bonded to a hydroxo-bridged dimer which is based on fac-octahedral co-ordination. In (1)(X = Cl, nL = 3C4H8O2) all H atoms of the dimer participate in bonds to 1,4-dioxan, and each dioxan O atom participates in one hydrogen bond. A layer structure results. In (2)(X = Cl, nL = 4C10H18O) and (3)(X = Br, nL = 4C10H18O) each ligand of the dimer participates in one hydrogen bond to an oxygen atom of the bulky cyclic ether 1,8-cineole; there is no extended structure. In (4)(X = Cl, nL = 4H2O) hydrogen bonding to lattice water links the dimers into chains, which are cross-linked by weak Cl … H2O bonds. In (5), tin tetrachloride pentahydrate, [SnCl4(OH2)2].3H2O, the cis-octahedral complexes are also linked into a three-dimensional net via H2O … H2O and Cl … H2O bonds. Crystals of (1) are triclinic, space group P1, with a= 9.033, b= 10.455, c= 8.942 Å, α= 115.34, β= 115.00, γ=91.65°, Z= 1, and R= 0.071 for 1 757 reflections; (2) : monoclinic, space group P21/c, with a= 12.82, b= 12.62, c= 15.70 Å, β= 92.4°, Z= 2, and R= 0.071 for 1 741 reflections; (3) : monoclinic, space group C2/c, with a= 18.73, b= 19.67, c= 14.37 Å, β= 81.2°, Z= 4, and R= 0.083 for 1 638 reflections; (4): monoclinic, space group P21/n, with a= 9.688, b= 6.517, c= 12.563 Å, β= 92.97°, Z= 2, and R= 0.084 for 892 reflections; (5): monoclinic, space group C2/c, with a= 12.379, b= 10.086, c= 8.701 Å, β= 104.13°, Z= 4, and R= 0.107 for 757 reflections.
