Crystal structures of two trinuclear Schiff-base copper(II) complexes

Copper Hydroxide Ethanedisulfonate: A Cationic Inorganic Layered Material for High‐Capacity Anion Exchange

“…Most of the longer bond distances correspond to weakly coordinating monodentate water ligands, which are easily dissociated and thus are not ascribed to covalent bonding. [25][26][27][28] The cuprate layers are thus not covalently bonded to the EDS anions, indicating this material is indeed a cationic 2-D layered inorganic structure. Two water molecules are intercalated in the interlamellar regions as for LDHs, and calculations of solvent-accessible void space per unit cell is 36.3 3 .…”

Synthesis, crystal structure and magnetic characterization of a novel linear trinuclear copper(II) complex bridged by phenoxy and benzyloxy oxygen atoms

“…The little zj 0 value illustrates the weak intermolecular interactions. The strong antiferromagnetic coupling is also found in the similar linear trinuclear copper(II) complexes [22,23]. Reedijk and his coworkers reported [24] that the magnetic behavior of these linear trinuclear Cu(II) systems based on planar CuO 2 …”

Use of Cu(II)-di-Schiff bases as metalloligands in the formation of complexes with Cu(II), Ni(II) and Zn(II) perchlorate

“…Moreover, when both the axial positions are coordinated either by two weakly coordinating monodentate ligands and by the bridging bidentate ligands the geometry is also linear. However, if only one monodentate ligand coordinates to an axial position of the central copper, its geometry may distort towards trigonal bipyramidal and consequently the structure becomes bent [23]. The structure can also be bent if the anionic coligands are strongly coordinating and occupy the equatorial positions [24,42].…”

“…it is other than Cu(II) ion. The molecular shapes of the trinuclear complexes show an interesting trend; the homonuclear Cu(II) complexes are usually linear [25][26][27][28] with some exceptions [23,24]. However, in the hetero trinuclear complexes when the bridging anionic co-ligands (nitrate, acetate, perchlorate etc.)…”

“…Among the divalent first transition elements, Cu(II) forms the most stable complexes with these Schiff bases [10][11][12][13] and therefore, these neutral Cu-chelates have been used frequently to form complex with another metal ions. In most of these complexes, the oxygen atoms of two ''metalloligands'' coordinate to a second ion to result in trinuclear complexes [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28]. These trinuclear complexes can be homonuclear i.e.…”
