S. Bhattacharya et al., SYNTHESIS AND CHARACTERIZATION OF CYCLOPENTADIENYLZIRCONIUM 1-PYRROLECARBOTHIOATES AND 1-PYRROLECARBODITHIOATES, Indian journal of chemistry. Sect. A: Inorganic, physical, theoretical & analytical, 33(12), 1994, pp. 1063-1068
Three series of complexes, viz., bis(eta(5)-cyclopentadienyl)zirconium
1-pyrrolecarbothioates and -dithioate, bis(eta(5)-cyclopentadienyl)ar
yloxyzirconium 1-pyrrolecarbodithioates and eta(5)-cyclopentadienylzir
conium 1-pyrrolecarbodithioates have been synthesized and characterize
d by infrared and H-1 NMR spectroscopy. The complex Cp(2)ZrC1(S2CNC4H4
) (II) crystallizes in the monoclinic space group P2(1)/n. The molecul
ar structure reveals a bent metallocene structure with the S2-CNC4H4 l
igand bidentately bonded to the Zr atom.
