A Crown-Linked Donor-Acceptor Assembly Containing Re^I(diimine)(CO)₃Cl and Nitrobenzene Components

The structure of the title assembly, tricarbonylchloro[16-nitro-3,6,9,12,20,23,26,29-octaoxa-34,37-diazatetracyclo[34.3.1.1^14,18.1^31,35]dotetraconta- 1(39),14,16,18 (41),31,33,35 (42),36 (40),37-nonaene- 2,13,19,30-tetraone]rhenium(I), C₃₅H₃₃ClN₃O₁₇Re, has been determined via a single-crystal diffraction study. The rhenium ion is octahedrally coordinated. The bidentate bipyridine/crown ether/nitrobenzene assembly is folded such that the pyridyl rings and nitrobenzene moiety are almost coplanar.
