RESUMO
A new bulky pyrene-derived elongated cross-shaped organic scaffold was successfully incorporated into a highly porous, noninterpenetrated square-grid copper(II)-organic framework material with the unprecedentedly huge dimensions of 25.5 x 25.5 A(2), while the layer-to-layer NH...N interaction leads to a unique hydrogen-bonded 6(4).8(2)-nbo net.

The self-assembly of rhenium-based rectangular boxes with a large inner cavity can be achieved via a simple one-step synthetic route; these molecules selectively recognize planar aromatic molecules, benzene in particular.

A triangular metalloprism, [((CO)3Re(mu-2)Re(CO)3)3(mu3-1)2], self-assembled from Re2(CO)10, 2,4,6-tri-4-pyridyl-1,3,5-triazine (tpt, 1), and indigo (H2(2)), represents a fairly novel example of strong face-to-face pi-pi interactions between the central triazine rings of the tpt ligands that bow significantly inward distorting the prismatic structure.
