%X The X-ray crystal structures of 5b,6,12b,13-tetrahydropentaleno&#91;1,2-b:4,5-b&acute;&#93;diquinoline 5,12-dioxide (5) and (6&#945;,7&#945;,14&#945;,15&#945;)-7,15-dibromo-6,7,14,15-tetrahydro-6,14-methanocycloocta&#91;1,2-b:5,6-b&acute;&#93;diquinoline 5,13- dioxide (6) reveal two new packing modes of potential importance as supramolecular synthons for molecular assembly. Both involve intermolecular edge&#8211;edge association of an aryl ring and an N-oxide functionality. One is a bifurcated Ar&#8211;H&#183;&#183;&#183;O(N)&#183;&#183;&#183;H&#8211;Ar interaction which on repetition gives infinite chains of the molecules. The second is a 10-membered centrosymmetric dimer also involving Ar&#8211;H&#183;&#183;&#183;O&#8211;N interactions but which merely links two neighbouring molecules of (6). The latter arrangement is a structural analogue of a recently reported dimeric centrosymmetric eight-membered Ar&#8211;H&#183;&#183;&#183;N synthon.
