Synthesis and Properties of Double Complex Salts Containing the Cation [Co(NH3)6]3+

Abstract

A series of complexes [ëo(NH 3 ) 6 ] x [ML 6(4) ] y , where M is Fe(III) and Fe(II), Cr(III), Cu(II); L is CN -, NCS -, 1/2C 2 , are synthesized. Their IR spectra and thermal decomposition in air are studied, and interplanar distances in crystalline lattices of the complexes are determined. The compounds can be used as precursors for producing homogeneous bimetallic nanodimensional powders. O 4 2-

Structural study of the lanthanide phosphonate family [H3N(CH2)4NH3]Ln[hedpH][hedpH2]

“…Several DCS involving hexaammine cations and trisoxalate anions are reported in the literature [2,3]. However, only one study was devoted to the compound combining these ions [3].…”

“…However, only one study was devoted to the compound combining these ions [3]. The choice of the [Ir(NH 3 Safe storage and transportation are one of the limiting factors for a wide use of hydrogen as an energy carrier. Solid compounds like metal hydrides contribute a promising alternative for traditional hydrogen storage.…”

“…The 4 wt % hydrogen capacity for NaAlH 4 containing Ticatalyst, showed about 10 years ago [1] the potential for reversible hydrogen storage in complex hydrides. In the search for novel materials for hydrogen storage the mixed alanate LiMg(AlD 4 ) 3 has been considered [2][3]. LiMgAlD 6 was synthesized by using the ball milling technique.…”

“…LiMgAlD 6 was synthesized by using the ball milling technique. 3LiAlD 4 + MgCl 2 → 2LiCl + LiMg(AlD 4 ) 3 . The product was recrystallized in diethyl ether/toluene to increase the crystallinity and to remove LiCl.…”

“…Often, metal phosphonates exhibit polymeric structures consisting of chains, layers, or three-dimensional networks, but monomeric structures are also known. In particular, the tunable organic units in diphosphonate [R(PO 3 cations. Herein, we report the structural determination by synchrotron X-ray powder diffraction of all the members in this family (Ln: La, Tb, Yb, Sm, Nd, Pr, Gd, Eu, Er).…”
