Ternary graphite intercalation compounds (GICs), which consist of graphite, alkali Metal (Li; Na, cations, and organic cointercalates such as ethylehediamine (en) or tetrahydrofuran (thf), are useful precursors to graphene-based materials and tetraalkylammonium GICs. This study investigates the gallery arrangements and intercalate dynamics of the deuterated en(d4), thf(d8), piperazine(d10), or 1,4-diazabicyclo[2.2.2]octane(dabco)(d12) in ternary GICs containing Na+ or K+ cations using XRD and solid state Na-23 and H-2 NMR line-shape analyses. An en(d4)-graphite oxide (GO) intercalation compound and the trihexylmethyl(d3)-ammonium (thma) GIC were also prepared and evaluated by XRD and NMR. The H-2 NMR spectra exhibit a narrow peak ascribed to intercalates undergoing isotropic rotation and a broad powder pattern ascribed to intercalates.in a rigid state or undergoing uniaxial rotations. The thma intercalates in thrna(d3)-GIC and the en(d4) intercalates in en(d4)-GO are relatively mobile and can diffuse; this may arise because there are no alkali metal cations in the galleries. The molecular dynamics as well as the synthetic challenges presented by some GICs are explained in terms of different affinities of alkali metal cations to the cointercalates.
