A Novel Bilayer Cobalt(II)−Organic Framework with Nanoscale Channels Accommodating Large Organic Molecules

Abstract
A unique noninterpenetrated 2D bilayer cobalt(II)−organic framework, [{Co(dpe)(NO2−BDC)}·0.5(dpe)]n·nH2O (1), possessing nanoscale rectangular channels that clathrate large organic molecules, has been hydrothermally synthesized by reaction of cobalt(II) salt with 5-nitro-1,3-benzenedicarboxylic acid (NO2−H2BDC) and 1,2-bis(4-pyridyl)ethylene (dpe).
