A known doubly interpenetrated metal organic framework with the formula [Zn-2(ndc)(2)(bpy)] possesses minimal porosity when activated.

Abstract
A known doubly interpenetrated metal organic framework with the formula [Zn-2(ndc)(2)(bpy)] possesses minimal porosity when activated. We show not only that the material converts to its triply interpenetrated analogue upon desolvation, but also that the transformation occurs in a single-crystal to single-crystal manner under ambient conditions. The mechanism proposed for the conversion is supported by computational methods and by analogy with the solid-state behavior of an analogous system.
