Ferrocene-thiourea inclusion compound

Thiourea forms a layered lattice able to act as host for some organometallic guest molecules. The ferrocene-thiourea inclusion compound has been investigated by spectroscopic methods (NMR, Mossbauer) and it has been shown that the thiourea host structure is preserved [492-502]. Other inclusion compounds of thiourea with organometallics such as ( /" -l,3-cyclohexadiene)Mn(CO)3, (7/ -C6H6)Cr(CO)3, (/ -l,3-cyclohexadiene)Fe(CO)3, and t/ -C(CH2)3Fe(CO)3 have been reported [503, 504]. 

NMR also has been used to further elucidate the structure and dynamic state of the ferrocene-thiourea inclusion compound [21,22] previously studied by Mossbauer techniques [23], [24] and C [25] NMR. First of all, a new single crystal Mossbauer... 

Metallocenes (but only with unsubstituted cyclopentadienyl rings) also form thiourea inclusion compounds. X-ray diffraction and Mdssbauer data on the ferrocene inclusion compound show that at 295 K the guest molecules are orientationally disordered at the sites of 32 symmetry. A phase change at 162 K generates a more ordered structure78).
