First high thermally stable organo–inorganic 3D polymer scandium derivative as a heterogeneous Lewis acid catalyst

Sc2(OOCC2H4COO)2.5(OH), a new hybrid organic–inorganic polymer, has been hydrothermally obtained; the crystal structure of this material has been established by single crystal X-ray diffraction; having high thermal stability it can be used as an effective Lewis acid catalyst and can be easily recycled and reused without any appreciable loss in activity.
