Abstract
A Co(II)-Ti(IV) heterometallic approach is successfully adopted to synthesize charge-neutral metal-organic frameworks based on oxo-centered trinuclear cluster and linear dicarboxylate linkers. Unlike their homonuclear predecessors, the cobalt-titanium-organic frameworks not only display a permanent porosity but also show an irreversible phase transition between two stable forms as unambiguously characterized by single-crystal and powder X-ray diffraction studies.
