Synthesis and characterization of cyano-bridged polynuclear [Cu(dmpn)2]3[Co(CN)6]2·12H2O and trinuclear [Cu(dmpn)2]2[Co(CN)6]·ClO4·3H2O complexes

Funktionale poröse Koordinationspolymere

“…[58][59][60][61] Cyanometallat-Anionen können vielfältige Geometrien einnehmen: z. B. lineare wie bei [M(CN) 2 ] À (M = Au, [62,63] Ag [64][65][66] ), trigonale wie bei [Cu(CN) 3 ] 2À , [67] tetraedrische wie bei [Cd(CN) 4 ] 2À , [68][69][70][71] quadratisch-planare wie bei [M(CN) 4 ] 2À (M = Ni, [41] Pd, [72][73][74] Pt [72,75] ), oktaedrische wie bei [M(CN) 6 ] 3À (M = Fe, [76][77][78][79][80] Co, [76,81,82] Cr, [83][84][85] Mn [86,87] ) und pentagonal-bipyramidale wie bei [Mo (CN) 7 ] 4À . [88][89][90][91] Insbesondere das Octacyanometallat-Ion [M(CN) 8 ] nÀ (M = Mo, W) bildet mehrere unterschiedliche Geometrien aus (quadratisch-antiprismatische, dodekaedrische, zweifach über-dachte trigonal-prismatische).…”

Performances and thermal stability of LiCoO2 cathodes encapsulated by a new gel polymer electrolyte

“…It is possibly expected that the modified LiCoO 2 would encounter the gel polymer electrolyte rather than directly the violent liquid elec- trolyte, which suggest that they may go through the less vigorous exothermic reaction. Furthermore, considering the previous publications [17] that the cyano groups are known to easily form a kind of coordinated complexes with transition metal ions such as cobalt, nickel, and so on, it is assumed that the cobalt cations in the LiCoO 2 could interact with the CN groups of cPVA-based gel polymer electrolytes, which might influence the structural stability of the delithiated LiCoO 2 as well as the surface reaction with the liquid electrolytes. The details on the interfacial phenomena between the delithiated LiCoO 2 and the cPVA-based gel polymer electrolytes will be further investigated in the next study.…”

Synthesis, spectroscopic, and structural aspects of two trinuclear cyano-bridged heterometallic complexes

“…The O(3) water molecule forms two donor interactions and bridges two cyanide nitrogen atoms, one intramolecularly to N(12) and another intermolecularly to N(12) that results in the formation of a centrosymmet- Table 3 Bond lengths (Å) and bond angles ( • ) for complex 2 X-ray crystallographic study shows that the complex 2 ( Fig. 2) [36][37][38][39][40]. There is only one trifluoro acetate and three water molecules in the asymmetric unit.…”
