Abstract


Coordination compounds derived from 2-guanidinobenzimidazole 1 and R2SnCl2 (2 R = Me, 3 R = Bu, 4 R = Ph), and SnCl4 7 were prepared and their structures investigated by 1H, 13C, 119Sn, 15N NMR, mass spectrometry (FAB or EI), infrared, and elemental analysis. The NMR data suggest pentacoordinated (5 and 6) or hexacoordinated tin atoms 24 and 7. In all cases, 2-guanidinobenzimidazole acts as a bidentate ligand. In the solid state, 24 and 7 are associated by bridging chlorine atoms in polymeric chains.
