摘要
In the title compound, [Ca(C19H11F2O2)2(CH3OH)4]﹞4CH3OH, the Ca2+ ion is located on an inversion centre and is hexacoordinated by two O atoms of two 4,4∩∩-difluoro-1,1∩:3∩,1∩∩-terphenyl-2∩-carboxylate ligands and four O atoms of four methanol ligands, forming a CaO6 polyhedron with a slightly distorted octahedral coordination geometry. The Ca〞O〞C angle between the carboxylate group and the calcium ion is 171.8 (2)～. Two types of intermolecular hydrogen-bond interactions (C=O...H and O〞H...O) between the carboxylate ligand, the methanol solvent molecules and the coordinating methanol ligands generate a two-dimensional network parallel to (001).
