Abstract

The asymmetric unit of the title polymeric compound, [Li2(C 16H11N2O2)2(C 16H12N2O2)2(CH 3CH2OH)2] n , contains two Li I ions, two 3-(1-phenyl-1H-pyrazol-3-yl)benzoate ions, two 3-(1-phenyl-1H-pyrazol-3-yl)benzoic acid molecules and two ethanol molecules. In the crystal structure, each of the two LiI ions has a distorted tetra-hedral geometry, coordinated by two carboxyl-ate O atoms, one carboxyl O atom and one ethanol O atom. The carboxyl-ate group bridges the LiI ions, forming a one-dimensional polymeric chain along [100]. The crystal structure is further stabilized by O - H?O and C - H?N hydrogen bonding, and ?-? inter-actions with centroid-centroid distances in the range 3.6534 (13)-3.8374 (13) . 2009 Fun et al.
