A three-dimensional (3D) porous structure of [Cu-3(mu(3)-OH)(mu(2)-O)(dmtrz)(2)(HCOO)(mu(2)-H2O)(H2O)(3)]center dot H2O (1) has been in situ solvothermally synthesized. In 1, the trinuclear triangular [Cu-3(mu(3)-OH)(mu(2)-O)(dmtrz)(2)] cluster connects itself infinitely, resulting in the type-II channel structure, which is different from that of the rigid type-I channel structure reported previously. Reversible dehydration and rehydration induced crystal-to- amorphous-like phase transformation for structure 1 has been observed and confirmed by PXRD patterns and gas adsorption. Furthermore, as a response to the structural transformation, the stimuli-induced modulation of magnetic properties have been observed.
