(Acetylacetonato-κ²O,O′)aqua[2-(2-nitrophenoxy)-N′-(2-oxidobenzylidene-κO)acetohydrazidato-κ²O,N′]manganese(III)

Abstract

In the title complex, [Mn(C15H11N3O5)(C5H7O2)(H2O)], the MnIII ion has a distorted octa­hedral coordination geometry. It is coordinated by a phen­oxy O atom, a hydrazine N atom and a carbonyl O atom of the 2-(2-nitro­phen­oxy)-N′-(2-oxidobenzyl­idene-κO)acetohydrazidate dianion, by two O atoms of the acetyl­acetonate anion and by the O atom of a coordinated water mol­ecule. In the crystal structure, complex mol­ecules are linked into centrosymmetric dimeric units through four inter­molecular O—H⋯O hydrogen bonds involving both H atoms of the coordinated water mol­ecule.

A novel one-dimensional copper(II) coordination polymer and a trinuclear nickel(II) complex with a one-dimensional hydrogen-bonded structure

“…Long, and presumably weak, bonding interactions between Cu II and ether oxygen have also been encountered in the complex [Cu(dboa)(C 6 H 5 NH 2 )] 2 Á-C 6 H 5 NH 2 [H 2 dboa is 2,2 0 -(1,2-phenylenedioxy)diacetic acid], in which the corresponding distance is 2.484 Å (McCann et al, 1995). However, in reported metal-hydrazone complexes containing phenoxy groups, these potential donors have not been found to coordinate to the metal atoms (Chen, 2008;Chen & Liu, 2004, 2006Gao et al, 2004;Li & Liu, 2004;Sun et al, 2005;Wang & Lian, 2013;Xiao, 2009;Zhang, 2006). Furthermore, these hydrazone ligands tend to form discrete metal compounds.…”
