Electrochemical Controllable Synthesis of Bismuth Hexacyanoferrate(II) Nanoplates and Its Application in Electrocatalysis

“…To the best of our knowledge, there is no literature on bismuth hexacyanoferrate(II), and only two are found on and c ) 13.67 Å). 26,27 On the basis that the atomic radii of Bi 3+ and Ln 3+ ions are approximately equal 28 and XRD patterns of Ln-K ferrocyanides correspond to a hexagonal unit, it may be interpreted that bismuth hexacyanoferrate(II) has a similar XRD mode with the Ln-K ferrocyanides. Through careful inspection of the JCPDs of lanthanide ferrocyanides, we find that almost all of the detected peaks are indexed as the hexagonal YbHCF (JCPDs 43-0767) with the lattice constants of a and c of 7.239 and 13.42 Å, respectively; the lattice constants of asprepared is comparable to that of hexagonal YbHCF.…”

Luminescence and crystal field analysis of Eu3+ in Eu[Co(CN)6]·4H2O

“…The crystal structures of Ln[M(CN) 6 ] Á 4H 2 O (M ¼ Co, Fe) have been studied for several systems. All of the systems M ¼ Co, with Ln ¼ Nd [5], Sm [6] and Er [7], as well as analogous Ln ¼ Fe systems [4] and BiCo(CN) 6 Á 4H 2 O [8] crystallize in the space group CmCm, Z ¼ 2. The Ln 3+ ion is 8-coordinated to six N atoms of six CN ligands as well as to two O atoms of water molecules in a Ln(NC) 6 (H 2 O) 2 square antiprismatic arrangement of approximate D 4d symmetry, but with exact C 2v (m2 m) site symmetry.…”
