Interaction of MoS 2 single-layer dispersions with Cu(II) or Ag(I) salts results in formation of ternary metal sulfides. Upon this, reduction of Cu(II) to Cu(I) and reduction of part of Ag(I) to Ag(0) occur. The structural features of the compounds are discussed on the basis of XRD, electron diffraction, EXAFS and XPS data.

The interaction of MoS 2 single-layer dispersion with 1,10-phenanthroline has been studied over the pH range 0–11. Only protonated phenanthroline initiates flocculation of dispersion and formation of intercalation compounds. Two intercalated phases containing respectively 0.31–0.35 and 0.1 mol of phenanthroline per mol MoS 2 have been isolated. In the first one (interlayer spacing c = 14.92–15.56 A) the planar organic species are inclinated with respect to MoS 2 layers. In the second one ( c = 9.7 A) these moieties are oriented parallel to the layers.

Intercalation compounds of MoS2 with monomeric or OH-bridged dimeric ruthenium arene cationic complexes have been obtained by interaction of MoS2 single-layer dispersions with aqueous solutions of [(arene)Ru(H2O)3 ]SO4 [arene=C6H6 , C6H2Me4-1,2,4,5, C6H4Me-1-Pri-4]. The structural arrangement of these intercalation compounds is discussed on the basis of XRD and EXAFS data. The arene ligands are orientated roughly perpendicular to the MoS2 slabs. Their nature determines the interlayer spacing as well as the intercalated cation content. Heating removes the organic ligands, while ruthenium-containing species remain in the van der Waals space of MoS2.

Restacking of exfoliated MoS2 in the presence of cationic metal complexes (M ˭Fe, Co, Ni, Ru) or metallic cations (M ˭Mn, Fe Co, Ni) leads to nanocomposite materials consisting of alternating layers of molybdenum disulfide and metal complex compounds or metal hydroxide clusters respectively.
