Abstract
Two new heptacoordinated organotin complexes, [MeSnCl(Hdaptsc)]Cl.MeOH (1) and MeSnCl(H2dapsc)]Cl2.2H2O (2), have been prepared from MeSnCl3 and H-2daptsc and H-2dapsc, respectively. Single crystal X-ray diffra ction studies showed them to be approximately pentagonal bipyramidal ( PBP), with the organic ligands lying in the equatorial plane. H-2dapts c and SnCl4 form a complex with the formula [ClSnCl(Hdaptsc)]Cl (3), w hich is presumed to have an analogous PBP structure. On the other hand , the complex obtained from H-2dapsc and Me2SnCl2 is tentatively formu lated as [(Me2SnCl2)2(H2dapsc)] (4), and Sn-119 Mossbauer spectroscopi c evidence suggests an octahedral coordination for the two tin atoms.
