Interpenetration in [Cd(isonicotinate)2(1,2-bis(4-pyridyl)- ethane)0.5(H2O)]n, a novel octahedral polymer containing an unusual two-dimensional bilayer motif generated by self-assembly of rectangle building blocks

A hydrothermally synthesized mixed-ligand molecular solid composed of pillared bilayers has been formulated; it presents a new remarkable three-dimensional architecture sustained by the catenation of two-fold decked layers, and exhibits intense photoluminescence upon photoexcitation at 314 nm.
