The reactions of the open-cage fullerene, MMK-9, with
an open 12-membered ring on its surface and silver(I) salts have been
examined. The structure of MMK-9 itself has been determined
by single-crystal X-ray diffraction. MMK-9 reacts with
silver trifluoroacetate in air to form the dimer, {MMK-9(OCH3)5Ag(AgO2CCF3)}2. Remarkably, five MeO groups have added to the surface of
the open cage in a pattern that surrounds a pentagon immediately adjacent
to the opening in the cage. Dioxygen has been implicated as the oxidant
in this unusual addition of five groups to the open cage. Two silver
ions connected to each other by a short argentophillic interaction
reside at the core of the centrosymmetric dimer. The reaction of silver
nitrate with MMK-9 yields the crystalline polymer, [{MMK-9(OCH3)5Ag(AgOCH3)}2·H2O]n. This polymer
consists of dimeric {MMK-9(OCH3)5Ag}2 units that are connected into strands through silver
ions, which are chelated by the amine functions of one open cage and
bound in η2-fashion to a pair of carbon atoms on an adjacent open cage.
