Abstract
The synthesis and the crystal structures of several wheel-and-axle metaleorganic (waamo) complexes are studied. The design of such systems is basically constituted by the binding between two Ru(II)(pcymene) Cl2 units (wheels) and an organic spacer (axle), bearing pyridinic and/or cyano functions. Particular attention is given to the solid-state organization of the waamo complexes and to their propensity to create acceptors sites for guest species The inverted piano-stool motif, a characteristic synthon of half-sandwich ruthenium units, is always observed here, generating well defined layers of host molecules. Both polycatenated and hosteguest systems were generated in order to achieve a compact packing.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
