IUPAC-NIST solubility data series. 73. Metal and ammonium formate systems

This volume reviews the metal and ammonium formate solubility data publishe d up to 1995. So far as the editors are aware, all the solubility data publ ished during this period have been reviewed. Preference has been given to d ata published in numerical form. Data that appeared only in graphical form may not appear in this volume. In each section the metal atoms are arranged in the order (group) in which they appear in the Periodic Table. Metal ato ms are arranged in the order (group) in which they appear in the Periodic T able. Metal formates are crystalline solids having some interesting chemica l and physical properties. Several of these salts are important because the y have nonlinear optical properties. Specific examples are: LiCHO2.H2O (3), NaCHO2 (4), Sr(CHO2)(2);, and Sr(CHO2)(2). 2H(2)O, Ba(CHO2)(2), formates o f Sc, Y and the rare earth elements having the general formula Me(CHO2)(3). nH(2)O (where Me=Sc, Y, La, Ce, Pr, Nd, Sm...Lu) and some double salts and mixed salts such as NaCd(CHO2)(3), BaCd(CHO2)(4). 2H(2)O and Li0.9Na0.1CHO 2. Some metal formates have useful electric or magnetic characteristics. Th us, Cu(CHO2)(2). 4H(2)O has ferroelectric properties, Cu(CHO2)(2) is ferrom agnetic, Mn(CHO2)(2). 2H(2)O is antiferromagnetic, CuBa2(CHO2)(6). 4H(2)O i s paramagnetic, and the formates of Ca, Cd, and Sr have elastic and thermop lastic properties. Bivalent metal formates could be used as precursors for the production of catalysts because they show excellent miscibility in the solid state, i.e., they form mixed crystals that dissociate at relatively l ow temperatures (about 300 degreesC) to form the respective oxides and mixe d oxides. There are also additional smaller-scale uses of metal formates. T he wide interest in the applications and uses of metal formates will lead t o an interest in seeking methods for the preparation of these materials. So lubility data for the metal formates will be helpful in devising the method s of preparation. Therefore, this volume has been prepared to present and e valuate solubility data for the binary, ternary and multicomponent systems containing metal formates in aqueous and in nonaqueous solutions.
