A novel stable donor/acceptor-supported Mn Imetallasilanone 3 was synthesized. The intramolecular silanone-Mn I interaction induces a highly strained three-membered cyclic structure, leading to an exceptionally high reactivity of 3 as a donor/acceptor complex of silanone. Indeed, metallasilanone 3 readily reacts with various small molecules such as H 2 or ethylene gas in mild conditions.

Molecules in each crystal showed important differences in their crystal packing and molecular conformations, especially in the positions adopted by the benzylidene moiety. Calorimetric and powder X-ray diffraction experiments revealed that, after desolvation, all but one of the solvates undergo a phase transition toward a crystalline solvent-free form. The analysis of these arrays, phase transitions, and the accompanying conformational changes can help to understand the interplay among the solvent, the framework flexibility, and the intermolecular interactions in the solid-state structure of biologically active molecules.
