Organometallic compounds in layered chalcogenides, oxohalides, and oxides

2 Organometallic compounds in layered chalcogenides, oxohalides, and oxides 

Intercalation compounds contain a rigid bidimensional crystalline lattice (matrix) which can incorporate molecular or ionic species between the layers to form a peculiar type of host-guest complex [297-299]. Intercalation of metallocenes into various inorganic hosts lattices has been the subject of much attention in recent years [300-304]. 

Intercalation of organometallic compounds modifies the physical properties of the host and has been used to produce new materials with potential uses as heterogeneous catalysts or in electrochemical applications [305]. The intercalation is reversible and the integrity of the host lattice is preserved. 

The change of electric properties and resulting mixed valence as a result of charge transfer from host to guest have been carefully investigated in SnS2-A Se c(CoCp2)o33 [321]. 

Intercalates of bis(benzene)molybdenum, ( -cyclopentadienyl)titanium( 7 -cyclooctatetraene) and ( -methylcyclopentadienyl)tungsten( / -cycloheptatrienyl) into SnS2 and SnSe2 have also been investigated in detail [314, 320].
