Direct-mixingassembly of a magnesium coordination complex as recyclable water adsorbent,

Mechanochemistry: opportunities for new and cleaner synthesis

“…[262] Further use of the acetate ion as a base is illustrated by the reaction of copper acetate with alanine: [263] Cu(OAc) 2 ·H 2 O + 2Hala → Cu(ala) 2 + 2HOAc + H 2 O and the reaction of nickel acetate with dimethylglyoxime to form [Ni(Hdmg) 2 ] [249] or with nicotinic acid to form nickel bis(nicotinate) [264] (the same researchers have reported very similar results with Ca, [265] Zn, [266] Mn and Mg [267] ). A number of metal compounds bearing substituted acac ligands are formed on grinding M(OAc 2 ) (M = Mn, Cu, Zn) with the protonated proligand.…”

A novel three-dimensional SrII coordination polymer based on benzene-1,2,4,5-tetracarboxylate: hydrothermal synthesis, crystal structure and spectroscopic and thermal studies

“…In the previously reported coordination polymer phases containing the pyromellitic acid ligand, it has been observed to link between two and ten metal centres (Wen et al, 2007;Ruiz-Perez et al, 2004). Additionally, changes in the pH levels during self-assembly can afford not only incorporation of tetraanionic BTEC 4À ligands (Wen et al, 2007;Ruiz-Perez et al, 2004;Lu et al, 2005;Yang et al, 2005;Ganesan et al, 2004;Kumagai et al, 2002;Liu et al, 2010;Luo & Batten, 2010;Zhang et al, 2010), but also trianionic HBTEC 3À (Majunder et al, 2006;Yang et al, 2010), dianionic H 2 BTEC 2À (Felix et al, 2001) and monoanionic H 3 BTEC À ligands (Zhang et al, 2009). Very few examples of strontium-based structures have been reported in the literature for these ligands (Dan et al, 2006;Christgau et al, 2006;Lo et al, 2011;Balegroune et al, 2011;Liu et al, 2005;Zima et al, 2007;Williams et al, 2008).…”

Synthesis, supramolecular structure and thermal study of a new dinuclear zinc(II) complex derived from benzene-1,2,4,5-tetracarboxylic acid

“…As for examples, a number of polymeric zinc(II) complexes derived from benzene-1,2,4,5-tetracarboxylic acid (H 4 L) have been reported so far [15][16][17][18][19][20][21][22][23][24][25][26][27][28]. However, also few dimeric complexes containing this tetracarboxylic acid (H 4 L) are reported [29][30][31][32][33][34][35][36][37] but not with zinc(II) ions. We anticipated that the reaction of zinc(II) salt with this carboxylic acid (H 4 L) may also produce dinuclear complexes which can generate interesting supramolecular structures via noncovalent interactions.…”
