Hydrolysis to a Complex with a Central, Octahedral (μ₆‐O)In₆ Unit

Abstract

Hitherto unknown for main group elements was the structural element M6O13, which has now been found in the cation 1, taci = 1,3,5-triamino-1,3,5-trideoxyinositol. In the In6O13 core with a μ6-oxo center and approximate Oh symmetry, the OIn6 unit is completely shielded by the six-coordinate (taci–3 H) ligands, which explains the surprising stability of 1 toward further hydrolysis.
