A number of complexes of FeCl2 and FeBr2 with amides, ureas, aniline, and benzothiazole have been prepared and characterized by means of Mössbauer and i.r. spectroscopy, and magnetic measurements. The stoichiometries FeX2L, FeX2L2, FeX2L3, FeX2L4, and FeX2L6 have been found in which the iron is six coordinate. With the exception of an isobutyramide complex which is formulated as [Fe(BUA)6][FeCl4], complexes of the first three types are polymeric with bridging halogens, while FeX2L4 is monomeric and FeX2L6 is formulated as [FeL6]Cl2.

Elemental Analyses

Tetranuclear hetero-metal MnIII2NiII2 complexes, [Mn2Ni2(L)4(OAc)2] (1) and [Mn2Ni2(L)4(NO3)2] (2) [H2L = N-(2-hydroxymethylphenyl)-5,6-benzosalicylideneimine], have been synthesized and characterized by X-ray crystal structure analyses, infrared spectra, and elemental analyses. The structure analyses revealed that the complexes have a defective double-cubane metal core connected by μ3-alkoxo bridges. Complexes consist of two bis-μ-alkoxo bridged MnIIINiII heteronuclear units making a dimer-of-dimers structure. The double-cubane cores are significantly distorted due to an effect of syn–syn mode acetato or nitrato bridges. Magnetic measurements indicate that weak antiferromagnetic interactions (Mn-Ni = −0.66 ~ −4.19 cm–1) are dominant in the hetero-metal core.

Chromyl chloride reacts with formic and acetic acids to give products which contain the trinuclear cation [Cr3O(OOCR)6(RCOOH)3]+. The compounds have been characterized by elemental analyses, infrared spectral data, magnetic measurements and thermogravimetry.

Organic Products

Reaction of chromyl chloride with various donor molecules led to solid products of compositions CrO2Cl2.2D (D = acetone or dimethylsulfoxide), 2CrO2Cl2.3D (D = tetrahydrofuran, 1,4-dioxan, or 4-picoline), CrO2Cl2.D (D = diethyl ether, triphenylphosphine, or triphenylarsine), and 2CrO2Cl2.(C6H5)3N. Acetonitrile failed to react. Infrared and ultraviolet spectra, X-ray diffraction and magnetic measurements, and the organic products obtained on hydrolysis were interpreted as showing that none of these complexes are Lewis adducts of chromyl chloride, but that all contain chromium(IV).
