Resumo: | Two new cases of heptacoordination in organotin(IV) complexes are described. Both possess pentagonal bipyramidal geometry and show the organic groups on the axial positions, with the ligands forming five bonds to tin(IV) on the equatorial plane. The first complex, [nBu2Sn(H2daptsc)]Cl2 MeNO2 (1) is entirely new, whereas the second, [Me2Sn(H2dapsc)][Me2 SnCl4] (2), although previously reported, only now had its structure determined. In both 1 and 2 the heptacoordinate species are cationic, but whereas in 1 the counterion is simply Cl-, in 2 it is a complex anion, namely [Me2SnCl4]². |

Two new cases of heptacoordination in organotin(IV) complexes are described. Both possess pentagonal bipyramidal geometry and show the organic groups on the axial positions, with the ligands forming five bonds to tin(IV) on the equatorial plane. The first complex, [nBu2Sn(H2daptsc)]Cl2 MeNO2 (1) is entirely new, whereas the second, [Me2Sn(H2dapsc)][Me2 SnCl4] (2), although previously reported, only now had its structure determined. In both 1 and 2 the heptacoordinate species are cationic, but whereas in 1 the counterion is simply Cl-, in 2 it is a complex anion, namely [Me2SnCl4]². |
