A net gain: A kinetically assembled, but thermally stable network is obtained using the labile metal species [Cu4I4(PPh3)4]. The network uniquely adsorbs I2 by chemisorption through I3 formation. The chemisorbed I2 readily desorbs above 380 K owing to the dynamic motion of the framework. A thermodynamically assembled network physisorbs I2, which is an exact fit for the channel.
