Novel Sn(IV) complexes with the guanidine-quinoline hybrid ligand DMEGqu are reported. With SnCl4, SnBr4, Me2SnCl2, Me2SnBr2, and the 3,5-di-tert-butyl-catecholate coligand complexes with different donor sets were synthesized. Four of these tin compounds have been modelled by density functional theory. Additionally, a tetranuclear Sn(IV) oxocluster with a novel structure motif, a distorted hetero-adamantane with bridging oxido and hydroxido ligands, is presented.
