“…In recent years, a variety of metal-organic compound of pyrazine-2,3-dicarboxylic acid have been characterized crystallographically due to growing interest in supramolecular chemistry. Examples are including the calcium (Ptasiewicz-Bak & Leciejewicz, 1997a;Starosta & Leciejewicz, 2005), magnesium (Ptasiewicz-Bak & Leciejewicz, 1997b), sodium (Tombul et al 2006), caesium (Tombul et al 2007) and potassium (Tombul et al 2008) complexes. Continuation our research on Group I dicarboxylates, we present here the synthesis and crystal structure of the hydrated polymeric dinuclear lithium complex, (I), formed with pyrazine-2,3-dicarboxylic acid.…”

Crystal structure of caesium(I) hydrogen maleate, Cs(C4H3O4)

“…Although most of the studies conducted in this area is primarily focused on coordination polymers containing transition metals as connectors, such as Zn, Ni and Co [3,4], there is little attention on the Group Imetal [5,6]. As part of ongoing studies on Group Idicarboxylates [7][8][9], we present here the caesium complex formed with maleic acid. The asymmetric unit of the title compound contains one caesium cation, one hydrogen maleate anion.…”

The coordination polymer poly[(μ3-3-aminocarbonylpyrazine-2-carboxylato-κ3N1:O2:O2′)silver(I)]

“…For pyrazine-2,3-dicarboxamide, four Cu II structures (Mondal & Ray, 1977;Klein et al, 1983) with the ligand in an N,O-chelating mode and one Ag I structure (Massoud et al, 2009) with the ligand in an N:N 0 -bridging mode have been reported. In contrast, many compounds of pyrazine-2,3-dicarboxylic acid with alkali (Tombul et al, 2006(Tombul et al, , 2007Tombul, Gü ven & Bü yü kgü ngö r, 2008;Tombul, Gü ven & Svoboda, 2008;Tombul & Guven, 2009) and transition metals (Zou et al, 1998(Zou et al, , 1999Konar et al, 2004;Xu et al, 2008) have been synthesized and structurally characterized.…”
