Bis(methanol-κO)bis(1,2-diamino-2-hydroxyiminoethanone oximato-κ2N,N′)copper(II) bis(oxamide dioxime) methanol disolvate

“…So far, most of the published work concerns 4-coordinated transition metal oxamide oximate complexs (Endres, 1980;Endres & Schlicksupp, 1980;Endres et al, 1983). The 6-coordinated transition metal oxamide oximate complexes have not been reported hitherto (Bélombé et al, 2006;Belombe et al, 2007;Egharevba et al, 1982). We used oxamide oxime as ligands (Gunasekaran et al, 1995) and obtained green crystals of the title compound from a methanol solution.…”

catena-Poly[[[(oxamide dioxime-κ2N,N′)copper(II)]-μ-L-tartrato-κ4O1,O2:O3,O4] tetrahydrate]: a chiral nanochannel framework hosting solvent water molecules

“…The structure of (I), we believe, ought to be welcomed as another promising template system within the narrow class of materials (Akutsu-Sato et al, 2005;Rashid et al, 2001;Infantes & Motherwell, 2002;Mascal et al, 2006;Martin et al, 2007) that are needed to probe the feasibility of the challenging prospect of one-dimensional proton conduction in solids (one-dimensional PCS) (Belombe et al, 2007(Belombe et al, , 2008Bé lombé, Nenwa, Mbiangué, Bebga et al, 2009), a prospect that may be likened somewhat to the novel ionic high proton conduction as a function of surrounding humidity level newly documented in a metal-organic framework which hosts ammonium cations and water molecules within functionalized lattice channels (Pardo et al, 2011).…”

Monoclinic polymorph of poly[[di-μ-aqua-triaquadi-μ-oxalato-barium(II)copper(II)] monohydrate]

“…Herein, a new polymorph of (I) is reported which crystallizes in the monoclinic space group C2/c. It was obtained unintentionally from aqueous solution during an on-going study of oxalate-based multifunctional materials (Bélombé et al, 2003(Bélombé et al, , 2006Belombe, Nenwa, Bebga et al, 2007;Bélombé, Nenwa, Mbiangué et al, 2007;Nenwa, 2004), and is formulated as…”
