Synthesis and spectral characterization of alkaline earth metal complexes: Crystal structure of a Ca(II) hippuric acid complex

Bis(4,4′′-difluoro-1,1′:3′,1′′-terphenyl-2′-carboxylato-κO)tetrakis(methanol-κO)calcium methanol tetrasolvate

“…For mononuclear calcium complexes with carboxylate ligands, see: Perrin et al (2009); Godino Salido et al (2004); Huang et al (2010). For their polymerization behavior, see: Jisha et al (2010); Murugavel & Banerjee (2003); Yang et al (2004).…”

“…Data collection: SMART (Bruker, 2000); cell refinement: SAINT (Bruker, 2000); data reduction: SAINT; program(s) used to solve structure: SHELXS97 (Sheldrick, 2008); program(s) used to refine structure: SHELXL97 (Sheldrick, 2008); molecular graphics: Octahedral mononuclear transition metal complexes with ligated carboxylates are well known structure for basic of inorganic chemistry (Chavez et al, 2001;Kannan et al, 2011). Few mononuclear calcium complexes with carboxylate ligands (Perrin et al, 2009;Godino Salido et al, 2004;Huang et al, 2010) are reported possible due to easy polymerization behavior (Murugavel et al, 2003;Jisha et al, 2010;Yang et al, 2004). Here, we report the structure of an octahedrally coordinated Ca 2+ complex which crystallizes in the orthorhombic space group Pbca with one half molecule in the asymmetric unit.…”

Alkaline and alkaline earth metals

“…160 Alkaline earth metal (Mg Ca Sr and Ba) complexes of hippuric acid (hipH) have been synthesised. 161 Barium tetrametaphosphate hydrate Ba 2 (P 4 O 12 )Á3.5H 2 O has been synthesised as a single-phase crystalline powder starting from an aqueous solution of barium hydroxide and phosphorus pentoxide. 162 A calcium complex of 1,10-dithia-18-crown-6 has been reported.…”
