Transformation from non- to double-interpenetration in robust Cd(II) doubly-pillared-layered metal-organic frameworks.

Two known Cd(II) non-interpenetrated doubly-pillared metal organic frameworks are shown to undergo a change of degree of interpenetration upon loss of lattice solvent molecules to yield doubly-interpenetrated frameworks. The conversion is inferred from powder X-ray diffraction (PXRD) patterns and supported by additional evidence from single-crystal diffraction (SCD) data.
