Abstract

X-ray crystal structures of the coordination polymers [MII(NO3)2(1,2-bis(4-pyridyl)ethane) 1.5]n (MII = Co, Ni) (1a-d) reveal that they can exist as flexible bilayer architectures. An open framework form of the bilayer enclathrates small organic molecules, compounds 1b-d. A close-packed bilayer architecture in which no guest molecules can be incorporated is also observed, as exemplified by compound 1a. The size and shape of the channels in the open framework structures appears to be related to the inherent conformational flexibility of the 1,2-bis(4-pyridyl)ethane spacer ligand.
