“…These reduction products of the nickelate are of particular interest in that K3Ni(CN)4 is presumably a compound of univalent nickel, while K4Ni(CN)4 may perhaps be looked upon as a compound involving zerovalent nickel. Analogous reactions have been observed when potassium cyanonickelate was reduced by liquid ammonia solutions of calcium (19). On the other hand, the complex cyanides KAg(CN)2, K2Cd(CN)4, and K3Cu(CN)4 were reduced by liquid ammonia solutions of potassium to the pyrophoric elemental metals.…”

“…Compound 2 has been characterized , and proposed as an intermediate, whereas compound 3 has neither been isolated nor well characterized . On the other hand compound 4 , first discovered in 1942, has been shown to be active in hydrocyanation reactions; it can be obtained directly in solution by reduction of K 2 [Ni(CN) 4 ] with NaBH 4 or metallic zinc in the presence of KCN …”

“…A few interesting examples are described. The cyano complexes of nickel (O), nickel(I), and palladium (O) have been mentioned (15,16). These compounds are obtained by the reduction, with potassium in liquid ammonia, of complex cyanides containing the respective elements in their dipositive states.…”

“…The importance of the role of the solvent is clearly demonstrated by the fact that it is possible to isolate and study complex cyanides of nickel(O), nickel(I) (15) and palladium(O) (16) by the reduction in liquid ammonia of cyanides containing the metals in higher oxidation number. Aqueous solutions of the complex cyanide of nickel(I) have been obtained also, but they are rather unstable, partly because of the oxidizing action of water.…”

Unfamiliar oxidation states have been characterized principally by four types of evidence: (1) analytical data and chemical properties; (2) isomorphism with compounds containing atoms of known oxidation state; (3) 0>-CH-N^> (C) ,0H HO * Swann and Xanthakos (J. Am. Soc, 53, 400 [1931]) have been able to obtain cobalt(III) sulfate by the anodic oxidation of cobalt(II) sulfate in 10 N sulfuric acid. INTRODUCTION *5 The products of the thermal decomposition of the triiodide and bromide of samarium at 800-900 0 in a high vacuum are the dihalides and the corresponding free halogens. 43 Halides of dipositive ytterbium are prepared in a similar manner. 44 * Oxidation numbers as low as 1.9 have recently been obtained (Mazzitelli, M.S. thesis. University of Kansas, 1949). * The reducing power of the solution after electrolysis was determined by titration with iodine. * These data are taken from an article by Tsentnershver and Blumenthal, Bull, intern, acad. polonaise, classe sci. math, nat., 1933A, pp. 499-522. There is some disagreement with the earlier values for the melting points of Rb0 2 and Cs0 2 (see ref. 2c). Similar values for the heats of formation of the superoxides are given by de Forcrand, Compt. rend., 158, 991 (1914). * Yost, Russell, and Garner, The Rare Earth Elements and Their Compounds, p. 9.
