From molecules to aggregates

The preparation of organometallic oxides, imides and nitrides is described. The molecular structures of these compounds resemble those found in binary systems. However, due to the organic envelope of the molecular solids, the y are soluble in organic solvents, easy to crystallize and unambiguously ch aracterizable by single X-ray structural analysis and NMR investigations. M oreover, inorganic oxides can be incorporated in organometallic phosphonate s or organoalumoxanes. Herein we describe the organometallic phosphonates a s hosts with a hydrophobic exterior.
