Dihydroxides

Manganese Hydroxide. Manganese hydroxide [18933-05-6] is a weaMy amphoteric base having low solubihty in water. Mn(OH)2 crystals are reported to be almost pure white and darken on exposure to air. Manganese dihydroxide occurs in nature as the mineral pyrochroite and can also be prepared synthetically by reaction of manganese chloride and potassium hydroxide that is scmpulously free of oxygen. The entire reaction is conducted under reducing conditions (36). [Pg.506]

Stibonic and Stibinic Acids. The stibonic acids, RSbO(OH)2, and stibinic acids, R2SbO(OH), are quite different in stmcture from their phosphoms and arsenic analogues. The stibonic and stibinic acids are polymeric compounds of unknown stmcture and are very weak acids. lUPAC classifies them as oxide hydroxides rather than as acids. Thus CgH3SbO(OH)2 is named phenyl antimony dihydroxide oxide [535-46-6], the Chemical Abstracts n.2ixn.e is dihydroxyphenylstibine oxide [535-46-6], CgH OgSb. [Pg.208]

Compounds of the type R2Sb(0S02R )2, and R2Sb(02CR )2, where R is an alkyl or an aryl group, have been prepared from a dihydroxide or oxide and the... [Pg.209]

Triphenylbismuth oxide [7173-99-1/, C gH BiO, has been prepared from triphenylbismuth dicyanide [41083-16-3], C2QH25B1N2, and mercuric oxide (151), and from triphenylbismuth dichloride and moist silver oxide (152). The ir and Raman spectra of this compound suggest that it is polymeric and has Bi—O—Bi bonds (153). Triphenylbismuth dihydroxide, and triarylbismuth hydroxide haUdes, eg, triphenylbismuth hydroxide chloride... [Pg.133]

Triphenylarsine oxide is partly converted to the dihydroxide when heated with water. However, it is not hygroscopic under ordinary conditions. ... [Pg.50]

For vanadyl uroporphyrin1, spectra in alkaline medium are different from those in organic solvents or crystalline. 2 If a six-coordinate dihydroxide species [V(OH)2UroP] really forms, it would be the first example of a deoxygenated Viv complex bound to two OH- groups. However, the arguments presented leave the possibility of [VO(OH)UroP] in alkaline solution.882... [Pg.558]
