M. Absi et al., A CROWN-LINKED DONOR-ACCEPTOR ASSEMBLY CONTAINING RE-I(DIIMINE)(CO)(3)CL AND NITROBENZENE COMPONENTS, Acta crystallographica. Section C, Crystal structure communications, 53, 1997, pp. 1054-1055
The structure of the title assembly, 6,29-octaoxa-34,37-diazatetracycl
o[34.3.1.1(14,18) etraconta-1(39),14,16,18(41),-31,33,35(42),36(40), 3
7-nonaene-2, 13, 19, 30-tetrone]rhenium(I), [ReCl(C32H33N3O14)(CO)(3)]
, has been determined via a single-crystal diffraction study. The rhen
ium ion is octahedrally coordinated. The bidentate bipyridine/crown et
her/nitrobenzene assembly is folded such that the pyridyl rings and ni
trobenzene moiety are almost coplanar.
