Аннотация
Reactions of thienyl side-chain-functionalized cyclopentadienyl ligands C5H5C(R1R2)C4H3S [R1 = R2 = CH3 (1); R1 = CH3, R2 = C2H5 (2); R1 = R2 = C2H5 (3); R1, R2 = (CH2)5 (4)] with Mo(CO)6 in refluxing xylene gave the corresponding cyclopentadienyl dimolybdenum carbonyl complexes: [(η5-C5H4)C(R1R2)(C4H3S)Mo(CO)3]2 [R1 = R2 = CH3 (5); R1 = CH3, R2 = C2H5 (6); R1 = R2 = C2H5 (7); R1, R2 = (CH2)5 (8)]. They are characterized by elemental analysis, IR and 1H NMR spectra. The molecular structures of (5) and (8) are determined by single crystal X-ray diffraction.
