Mixed chloride/amine complexes of dimolybdenum(II,II). 4. rotational isomers of Mo (sub)2 Cl (sub)4 (R-py) (sub)4 (R-py = 4-picoline, 3,5-lutidine, and 4-tert-butylpyridine)

A study concerning preparation of quadruply bonded dimolybdenum complexes with alkyl-substituted pyridines is presented. X-ray diffraction has been used to examine crystalline structure of different compounds.
