CRYSTAL ENGINEERING: HONEYCOMB NETWORKS, MOLECULAR LAMINATES AND SUPRAMOLECULAR BOXES: C. V. Krishnamohan Sharma, Michael J. Zaworotko, Department of Chemistry, Saint Mary's University, Halifax, Nova Scotia, B3H 3C3, Canada

Possibly general strategies for constructing a variety of supramolecular architectures will be discussed. A schematic representation of each of these strategies is depicted below.

Honeycomb Networks: The modular self assembly of trigonal molecules (either with triple functional hydrogen bond donor or acceptor sites) with complementary linear `spacer' molecules results in hexagonal networks as shown in Scheme I.

Molecular Laminates: Alkyl group(s) that are supported by rigid two dimensional scaffolding may be used to generate a variety of molecular laminates by manipulating the nature of alkyl chain(s) (Scheme II).

Supramolecular Boxes: Alignment of corrugated sheets through directional forces precludes the expected close-packing between the layers, leading instead to formation of supramolecular boxes (Scheme III).
