Uhf. Bunz et V. Enkelmann, Structure elucidation, packing, and solid-state behavior of the Eglinton-Galbraith dimer, CHEM-EUR J, 5(1), 1999, pp. 263-266
Crystal structure, packing behavior, and solid-state activity of the cyclic
dimer 1 of ortho-diethynylbenzene are described. When crystallized in the
presence of TCNQ or hexafluorobenzene, 1 forms novel 1:1 molecular complexe
s in the solid state. The flat guests are inserted between the disklike mol
ecules of 1 so that mixed stacks are formed.
