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.
