Structural characterisation of organometallic intercalates of SnSe2 and ZrS2 by neutron and X-ray diffraction

Abstract

The synthesis of large, single crystals of ZrS2 intercalated with various organometallic sandwich compounds {[Co(η-C5H5)2], [Cr(η-C5H5)2], [Co(η-C5H4Me)2], [Mo(η-C6H6)2][W(η-C7H7)(η-C5H4Me)] and [Ti(η-C8H8)(η-C5H5)]} and of SnSe2 intercalated with [Co(η-C5H5)2] are described; results from both neutron and X-ray diffraction experiments reveal that for all the intercalates the organometallic guests reside with their metal-to-ring centroid axes parallel to the layers of the host lattice.
