Abstract

1,2-Diaminopropane (1,2-DAP) provides an unusual example of an organic co-intercalate where graphite intercalation compounds (GICs) show intra-gallery orientation dependant on the identity of the alkali metal cation intercalate (Li⁺, Na⁺, or K⁺). The GIC gallery heights, K(1,2-DAP)_yC_x = 0.697 nm and Li(1,2-DAP)_yC _x = 0.782 nm, indicate 1,2-DAP long axis orientations that are parallel or perpendicular to the graphene sheets, respectively.
