Synthesis and Crystal Structure of 1,3-Bis(5-nitrosalicylideneamino)-2-propanol

Synthesis and Crystal Structures of Dinuclear Cobalt(III) Complexes with 1,3-Bis(5-nitrosalicylideneamino)-2-propanol and 1,3-Bis(3-nitrosalicylideneamino)-2-propanol

“…4 Interestingly, this ligand takes a folded form with the two Schiff-base moieties. 1 A similar folded form was observed in the crystal structure of a related dinuclear manganese(III) complex with 1,3-bis-(salicylideneamino)-2-propanol. 5 In this study, we synthesized a cobalt complex by using H3b5nsalpr, so as to see what kind of species can be isolated, because there is no report concerning to crystal structure of a cobalt complex with H3b5nsalpr.…”

“…1 The H3b5nsalpr ligand is a pentadentate ligand, having two phenolic-oxygen and two imino-nitrogen donor-atoms and one set of bridging alcohol-oxygen donor atom to give dinuclear manganese(II) 2 and manganese(III) 3 complexes with tridentate O,N,O-chelates. The ligand also forms a mononuclear copper(II) complex with a tetradentate O,N,N,O-chelate, when the central bridging alcohol-oxygen atom cannot be deprotonated.…”

Tetranuclear Nickel(II) Complex with an Unsymmetrical Pentadentate Schiff-base Ligand Having a Defective Double-Cubane Core

“…[1][2][3][4][5][6] In the case of dinucleating Schiff-base ligands having a bridging group, such as alkoxido-oxygen, many dinuclear metal complexes were prepared and their magnetic properties were investigated. [3][4][5][6] Most of these dinucleating ligands are symmetrical concerning the bridging group, and afford dinuclear metal complexes with the same geometry for the two metal centers.…”

Dinuclear Assembly in a Copper(II) Complex with 1,3-Bis(pyrrole-2-methylideneamino)-2-propanol

“…[1][2][3][4][5][6] Recently, we isolated a nickel(II) complex with a compartmenttype Schiff-base ligand containing a pyrrole group, 1,3-bis(pyrrole-2-methylydeneamino)-2-propanol (H3bpmp), [Ni(Hbpmp)]·0.5CH3OH, which was thought to be interesting compared with a biologically important imidazole derivative ligand.7 X-ray crystallographic work revealed a mononuclear structure with a square-planar arrangement of the nickel(II) ion with a partially deprotonated Schiff-base ligand. In this study, we prepared a copper(II) complex with H3bpmp, [Cu(Hbpmp)]· 0.5C2H5OH ( Fig.…”
