Abstract: (NH₄)₂[Mo₂(OH)₂O₂(OH)₂Cl₄] (I) and [Mo₂O₄(OH)₂(H₂O)₄].4.5H₂O (II) were sepd. from (MoOCl₅)^-- solns. in HCl (<4N). A weak paramagnetism was detected in I, characteristic of a ferromagnetic, while II is a diamagnetic. Paramagnetic resonance absorption exists in I at 84 and 293°K. M.O. calcns. disclose that I is paramagnetic because of the weakness of the Mo-Mo bond and II is diamagnetic because of its strength. The calcd. M.O. agree well with the absorption spectra of the compds.
