A Single-Crystal Study of the Magnetic Behavior and Exchange Coupling in Cu2(OH)3NO3

Preparation, Characterization, andab initioX-Ray Powder Diffraction Study of Cu2(OH)3(CH3COO)·H2O

“…1.9 and a Weiss constant "!7(1) K are obtained. Very recently, a number of magnetic studies of the title compound (37) and of structural analogues have been performed on oriented single crystals (38) This effect is utmost importance in the preparation of over-exchanged Cu-ZSM-5 catalysts, where the copper loadings exceed the maximum amount permitted by the aluminium present in the framework of the ZSM-5 zeolite. The best over-exchanged catalysts are those where low-nuclearity copper species are exchanged before Cu (OH) (CH COO) · H O is formed; indeed, the precipitation of the basic copper acetate on the external surface and possibly at the intersection of the ZSM-5 zeolite channels leads, after its decomposition at high temperature, to CuO with consequent loss of surface area and porosity of the catalysts (10).…”

Lamellar nickel hydroxy-halides: anionic exchange synthesis, structural characterization and magnetic behavior

“…Layered Hydroxide Salts (LHSs) with the general formula M II (OH) 2Àx X x $nH 2 O (X ¼ anions like nitrate or carboxylate, M ¼ Ni, Co, Cu, and Zn) have been the subject of intense study in the past decade, [1][2][3][4][5][6][7][8][9][10][11][12][13] especially due to their peculiar anionic exchange properties 12,[14][15][16] which result in original tunable functional materials in various elds including electrodes in alkaline cells, 17,18 magnetism, 3,8,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] magneto-optics, 34,35 photovoltaics, 36 pressure induced transitions, 32 drug delivery, 37 sensors 38,39 and are also precursors of functional oxides. [40][41][42] The main synthesis route to these compounds consists of the neutralization of an aqueous solution of nitrate or acetate salt...…”

Layered nickel hydroxide salts: synthesis, characterization and magnetic behaviour in relation to the basal spacing

“…In this context, systems with M ~Cu and Co have been widely investigated over the past decade. [7][8][9][10][11] As regards nickel(II) compounds, the examples in the literature are scarce. Only Ni 2 (OH) 3 (NO 3 ) 12 and Ni 2 (OH) 3 -(C 12 H 25 SO 3 )?H 2 O 13 have been reported.…”
