We have synthesized and characterized the tertiary graphite intercalation compounds (mercurographitides) KHgC4 (stage 1) and KHgC8 (stage 2) based on HOPG. We also report the first measurement of the low temperature specific heat of these compounds b

The potassium hydrogenographitides, KH2/3C8 and K3H4/3C16, and potassium and rubidium mercurographitides have been extensively studied. In the hydrogenographitide series 1H n.m.r. is not observed, but e.p.r. shows metallic character in stage I and II

Superconductivity was observed in the graphite intercalation compounds, KHgC 8 and RbHgC 8 , using an AC induction technique. The transition temperatures were 1.90K and 1.44K for KHgC 8 and RbHgC 8 respectively. A full Meissner effect was observed fo

The metallic alloys are susceptible to intercalation into graphite to form ternary compounds. One can classify these compounds into three types: (1) the solid solutions where the intercalated monoatomic layers are alloys of the two metals; (2) the de

Several aspects of the binary metal graphite compounds are described, i.e. temperature and pressure conditions for the intercalation of pure metals into graphite, structures and stacking of the intercalated layers especially in the first stage compou

We have shown that the potassium and rubidium amalgams, KHg and RbHg, intercalate into graphite forming very metal-rich ternary compounds of general formula MHgC4 (first stage) and MHgC8 (second stage). The reaction provokes a very high c axis dilati

Potassium and rubidium amalgams are able to intercalate into graphite and produce ternary compounds of two types. With amalgams rich in alkali metal, binary compounds with small amounts of mercury in the intercalated layers are obtained: MC 8 (Hg). W

The formula of a first stage graphite-metal compound is written under the form of MC x . The interaction between the metal and graphite planes is in epitaxy which involves x as an integer: the metal atoms are in the potential wells formed by the hexa

Experimental results of X and neutron structural studies, 1H and 13C NMR and EPR measurements are given for two series of alkaline graphitides with H and Hg as third component. Hydrogen structure and position are proposed in KH 2 3 C8 and K3H 4 3 C16

Wahrend sich Hg allein nicht in Graphit einlagern kann, reagieren die Amalgame KHg und RbHg mit Graphit unter gleichzeitiger Einlagerung von Hg und dem Alkalimetall.
